To Access blocked sites: Use Calculator!!

When both Domain Name & IP Address are banned, Use Calculator to Access that Website

This unique Mathematics based trick will probably work when websites are blocked in your institution or corporate network based on the host name or their IP address.

The trick is to convert the human readable website address that's blocked (like Link:) into an IP address (208.75.184. 160) and again translate this value to a decimal address which is probably not blocked by the website filters.

Here's a step by step guide to render Link:. com to a decimal address:

How to Access Restricted Websites

1) get its IP address (216.178.39. 74), by pinging the name (if you have a direct internet connection) or if you only have access via a web proxy then find it out by using a networking website like network-tools. com.

2) start your PC's calculator, and change it to scientific mode (using the "View" menu)

3) enter each of the four IP octets, one by one, converting them to binary (enter number and click on the "Bin" radio button)

Thus 216.178.39.74 becomes

216 = 11011000

178 = 10110010

39 = 00100111

74 = 01001010  3/5/08 ~$~Rohit 

Notice how any binary numbers less than 8 digits long have had leading zeroes added to pad them out. Reassembled into IP address order, you get 11011000.10110010. 00100111. 01001010

4) Remove the dots, so you get one huge line of binary, thus: 1101100010110010001 0011101001010

5) Copy this binary string

6) Go to your scientific calculator, and hit the "Bin" button FIRST (as you are about to enter binary), THEN paste in the binary string.

7) Click on the "Dec" button on your calculator, and you will get the converted value of 3635554122

8) Add the hypertext protocol prefix and paste into your browser's address bar: Link:

Increase Virtual RAM - To Make Your System Faster

1) Hold down the 'Windows' Key and Press the 'Pause/Break' button at the top right of your keyboard.
Another way is Right-Clicking 'My Computer' and then Select 'Properties'.
2) Click on the 'Advanced' tab.
3) Under 'Performance', click 'Settings'.
4) Then click the 'Advanced' tab on the button that pops up.
5) Under 'Virtual Memory' at the bottom, click 'Change'.
6) Click the 'Custom Size' button.
7) For the initial size (depending on your HD space), type in anywhere from 1000-1500 (although I use Z000), and for the Maximum size type in anywhere from 2000-2500 (although I use 6000).
8) Click 'Set', and then exit out of all of the windows.
9) Finally, Restart your computer.
10) You now have a faster computer and 1-2GB of Virtual RAM..! 

                                                                         

Cracking Windows XP Password

Now just follow the steps n if u don understand just post so no worry....(you need 1 XP BOOTABLE DISK 4 THIS)

1. Place your Windows XP CD and start your comp (before that set your bios set to boot from CD)
2. Screen messages for booting is typically “Press any key to boot from cd”
3. The first screen will indicate that Setup is inspecting your system and loading files.
4. When you get to the Welcome setup screen press Enter to setup Windows now
5. The licensing Agreement comes next – Press F8 to accept it.
6. The next screen is the SETUP screen which gives you the option to do a Repair.It should read something like “if on of the following Windows XP installations is damaged, Setup can try to repair it” Use the up and down arrow keys to select your XP installation (in case you have more than one Windows on your comp – if you have one,it should already be selected) and PRESS R TO BEGIN REPAIR process.
7. Let the Repair run.
Setup will now check your disks and then start copying files which can take several minutes.
8. Shortly after the Copying Files stage, you will be required to reboot.(this will happen automatically – you will see a progress bar stating “Your computer will reboot in 15 seconds” 
9. During the reboot, do not make the mistake of “pressing any key” to booth from CD again! Setup will resume automatically with the standard billboard screens and you will notice INSTALLING WINDOWS is highlighted.
10. Keep YOUR EYE ON THE LOWER LEFT HAND SIDE OF THE SCREEN AND WHEN YOU SEE THE INSTALLING DEVICES progress bar, PRESS (SHIFT + F10).
This is security hole! A command console will now open up giving you the potential for wide access to your system.
11. At the prompt type NUSRMGR.CPL and press ENTER. Bingo! You have just gained graphical access to your User Accounts in the Control Panel.
12. Now simply pick the account you need to change and remove or change your password as you prefer.
If you want to log on without having to enter your new password, you can type userpasswords2 at the prompt and choose to log on without being asked for password.
After you’ve made tour changes close the windows, exit the command box and continue on with Repair.
13. Once Repair is done you will be able to log on with your new password (or with out if you chose not to be asked for password) and so lives go one.

Ways To Speed WinXP, Not only Defrag

Since defragging the disk won't do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance the performance and reliability of your customers' PCs. Best of all, most of them will cost you nothing.

1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.

2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.

3.) Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.

4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.

The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.

Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.

Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.

5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.

6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.

7.) Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.

8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.

9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.

10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.

11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.

12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.

13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.

14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.

15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.

16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.

17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.

18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.

19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.

20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.

21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.

22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.

23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.

Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.

Great Google Loopholes

 Google is an remarkably powerful tool that can ease and enhance your Internet exploration. Google's search options go beyond simple keywords, the Web, and even its own programmers. Let's look at some of Google's lesser-known options.

Syntax Search Tricks

Using a special syntax is a way to tell Google that you want to restrict your searches to certain elements or characteristics of Web pages. Google has a fairly complete list of its syntax elements at

www.google.com/help/operators.html

Here are some advanced operators that can help narrow down your search results.

Intitle: at the beginning of a query word or phrase (intitle:"Three Blind Mice") restricts your search results to just the titles of Web pages.

Intext: does the opposite of intitle:, searching only the body text, ignoring titles, links, and so forth. Intext: is perfect when what you're searching for might commonly appear in URLs. If you're looking for the term HTML, for example, and you don't want to get results such as

www.mysite.com/index.html

, you can enter intext:html.

Link: lets you see which pages are linking to your Web page or to another page you're interested in. For example, try typing in

link:http://www.pcmag.com

Try using site: (which restricts results to top-level domains) with intitle: to find certain types of pages. For example, get scholarly pages about Mark Twain by searching for intitle:"Mark Twain"site:edu. Experiment with mixing various elements; you'll develop several strategies for finding the stuff you want more effectively. The site: command is very helpful as an alternative to the mediocre search engines built into many sites.

Swiss Army Google

Google has a number of services that can help you accomplish tasks you may never have thought to use Google for. For example, the new calculator feature

(www.google.com/help/features.html#calculator)

lets you do both math and a variety of conversions from the search box. For extra fun, try the query "Answer to life the universe and everything."

Let Google help you figure out whether you've got the right spelling—and the right word—for your search. Enter a misspelled word or phrase into the query box (try "thre blund mise") and Google may suggest a proper spelling. This doesn't always succeed; it works best when the word you're searching for can be found in a dictionary. Once you search for a properly spelled word, look at the results page, which repeats your query. (If you're searching for "three blind mice," underneath the search window will appear a statement such as Searched the web for "three blind mice.") You'll discover that you can click on each word in your search phrase and get a definition from a dictionary.

Suppose you want to contact someone and don't have his phone number handy. Google can help you with that, too. Just enter a name, city, and state. (The city is optional, but you must enter a state.) If a phone number matches the listing, you'll see it at the top of the search results along with a map link to the address. If you'd rather restrict your results, use rphonebook: for residential listings or bphonebook: for business listings. If you'd rather use a search form for business phone listings, try Yellow Search

(www.buzztoolbox.com/google/yellowsearch.shtml).

Extended Googling

Google offers several services that give you a head start in focusing your search. Google Groups

(http://groups.google.com)

indexes literally millions of messages from decades of discussion on Usenet. Google even helps you with your shopping via two tools: Froogle

CODE

(http://froogle.google.com),

which indexes products from online stores, and Google Catalogs

CODE

(http://catalogs.google.com),

which features products from more 6,000 paper catalogs in a searchable index. And this only scratches the surface. You can get a complete list of Google's tools and services at

www.google.com/options/index.html

You're probably used to using Google in your browser. But have you ever thought of using Google outside your browser?

Google Alert

(www.googlealert.com)

monitors your search terms and e-mails you information about new additions to Google's Web index. (Google Alert is not affiliated with Google; it uses Google's Web services API to perform its searches.) If you're more interested in news stories than general Web content, check out the beta version of Google News Alerts

(www.google.com/newsalerts).

This service (which is affiliated with Google) will monitor up to 50 news queries per e-mail address and send you information about news stories that match your query. (Hint: Use the intitle: and source: syntax elements with Google News to limit the number of alerts you get.)

Google on the telephone? Yup. This service is brought to you by the folks at Google Labs

(http://labs.google.com),

a place for experimental Google ideas and features (which may come and go, so what's there at this writing might not be there when you decide to check it out). With Google Voice Search

(http://labs1.google.com/gvs.html),

you dial the Voice Search phone number, speak your keywords, and then click on the indicated link. Every time you say a new search term, the results page will refresh with your new query (you must have JavaScript enabled for this to work). Remember, this service is still in an experimental phase, so don't expect 100 percent success.

In 2002, Google released the Google API (application programming interface), a way for programmers to access Google's search engine results without violating the Google Terms of Service. A lot of people have created useful (and occasionally not-so-useful but interesting) applications not available from Google itself, such as Google Alert. For many applications, you'll need an API key, which is available free from

CODE

www.google.com/apis

See the figures for two more examples, and visit

www.pcmag.com/solutions

for more.

Thanks to its many different search properties, Google goes far beyond a regular search engine. Give the tricks in this article a try. You'll be amazed at how many different ways Google can improve your Internet searching.

Online Extra: More Google Tips

Here are a few more clever ways to tweak your Google searches.

Search Within a Timeframe

Daterange: (start date–end date). You can restrict your searches to pages that were indexed within a certain time period. Daterange: searches by when Google indexed a page, not when the page itself was created. This operator can help you ensure that results will have fresh content (by using recent dates), or you can use it to avoid a topic's current-news blizzard and concentrate only on older results. Daterange: is actually more useful if you go elsewhere to take advantage of it, because daterange: requires Julian dates, not standard Gregorian dates. You can find converters on the Web (such as

CODE

http://aa.usno.navy.mil/data/docs/JulianDate.html

excl.gif No Active Links, Read the Rules - Edit by Ninja excl.gif), but an easier way is to do a Google daterange: search by filling in a form at

www.researchbuzz.com/toolbox/goofresh.shtml or www.faganfinder.com/engines/google.shtml

If one special syntax element is good, two must be better, right? Sometimes. Though some operators can't be mixed (you can't use the link: operator with anything else) many can be, quickly narrowing your results to a less overwhelming number.

More Google API Applications

Staggernation.com offers three tools based on the Google API. The Google API Web Search by Host (GAWSH) lists the Web hosts of the results for a given query

(www.staggernation.com/gawsh/).

When you click on the triangle next to each host, you get a list of results for that host. The Google API Relation Browsing Outliner (GARBO) is a little more complicated: You enter a URL and choose whether you want pages that related to the URL or linked to the URL

(www.staggernation.com/garbo/).

Click on the triangle next to an URL to get a list of pages linked or related to that particular URL. CapeMail is an e-mail search application that allows you to send an e-mail to google@capeclear.com with the text of your query in the subject line and get the first ten results for that query back. Maybe it's not something you'd do every day, but if your cell phone does e-mail and doesn't do Web browsing, this is a very handy address to know.

Reasons Why Pc Crush.

Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."

You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?

1 Hardware conflict

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.

For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.

If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.

Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.

Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).

When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.

To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.

2 Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.

But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.

One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.

Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.

EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.

3 BIOS settings

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.

Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.

A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.

Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).

4 Hard disk drives

After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to

* Start-Programs-Accessories-System Tools-Disk Defragmenter

This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.

The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).

Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. This can be adjusted by going to

* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.

Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.

Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to

* Start-Programs-Accessories-System Tools-ScanDisk

Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.

5 Fatal OE exceptions and VXD errors

Fatal OE exception errors and VXD errors are often caused by video card problems.

These can often be resolved easily by reducing the resolution of the video display. Go to

* Start-Settings-Control Panel-Display-Settings

Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For most desktops, high colour 16-bit depth is adequate.

If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. Go to

* Start-Settings-Control Panel-System-Device Manager

Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.

If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse.

The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.

Another useful way to resolve video problems is to go to

* Start-Settings-Control Panel-System-Performance-Graphics

Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).

Look up your video card's manufacturer on the internet and search for the most recent drivers for it.

6 Viruses

Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to

* Start-Settings-Control Panel-Add/Remove Programs

Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.

A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.

An excellent antivirus programme is McAfee VirusScan by Network Associates ( www.nai.com). Another is Norton AntiVirus 2000, made by Symantec ( www.symantec.com).

7 Printers

The action of sending a document to print creates a bigger file, often called a postscript file.

Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer's performance.

If the printer is trying to print unusual characters, these might not be recognised, and can crash the computer. Sometimes printers will not recover from a crash because of confusion in the buffer. A good way to clear the buffer is to unplug the printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer's default settings and you may be able to carry on.

8 Software

A common cause of computer crash is faulty or badly-installed software. Often the problem can be cured by uninstalling the software and then reinstalling it. Use Norton Uninstall or Uninstall Shield to remove an application from your system properly. This will also remove references to the programme in the System Registry and leaves the way clear for a completely fresh copy.

The System Registry can be corrupted by old references to obsolete software that you thought was uninstalled. Use Reg Cleaner by Jouni Vuorio to clean up the System Registry and remove obsolete entries. It works on Windows 95, Windows 98, Windows 98 SE (Second Edition), Windows Millennium Edition (ME), NT4 and Windows 2000.

Read the instructions and use it carefully so you don't do permanent damage to the Registry. If the Registry is damaged you will have to reinstall your operating system. Reg Cleaner can be obtained from www.jv16.org

Often a Windows problem can be resolved by entering Safe Mode. This can be done during start-up. When you see the message "Starting Windows" press F4. This should take you into Safe Mode.

Safe Mode loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading properly.

Sometimes installing Windows is difficult because of unsuitable BIOS settings. If you keep getting SUWIN error messages (Windows setup) during the Windows installation, then try entering the BIOS and disabling the CPU internal cache. Try to disable the Level 2 (L2) cache if that doesn't work.

Remember to restore all the BIOS settings back to their former settings following installation.

9 Overheating

Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.

One remedy is to get a bigger better fan and install it on top of the CPU. Specialist cooling fans/heatsinks are available from www.computernerd.com or www.coolit.com

CPU problems can often be fixed by disabling the CPU internal cache in the BIOS. This will make the machine run more slowly, but it should also be more stable.

10 Power supply problems

With all the new construction going on around the country the steady supply of electricity has become disrupted. A power surge or spike can crash a computer as easily as a power cut.

If this has become a nuisance for you then consider buying a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.

It is a good investment if your data are critical, because a power cut will cause any unsaved data to be lost.

Have a Nice Day

Untold Windows Tips and Secrets By Ankit Fadia

Welcome to another Hacking Truths Manual. This time I have a collection of Tips and Tricks which no body normally knows, the secrets which Microsoft is afraid to tell the people, the information which you will seldom find all gathered up and arranged in a single file. To fully reap this Manual you need to have a basic understanding of the Windows Registry, as almost all the Tricks and Tips involve this file.

****************

Important Note: Before you read on, you need to keep one thing in mind. Whenever you make changes to the Windows Registry you need to Refresh it before the changes take place. Simply press F5 to refresh the registry and enable the changes. If this does not work Restart your system

Exiting Windows the Cool and Quick Way

Normally it takes a hell lot of time just Shutting down Windows, you have to move your mouse to the Start Button, click on it, move it again over Shut Down, click, then move it over the necessary option and click, then move the cursor over the OK button and once again (you guessed it) click.This whole process can be shortened by creating shortcuts on the Desktop which will shut down Windows at the click of a button. Start by creating a new shortcut( right click and select New> Shortcut). Then in the command line box, type (without the quotes.)

'C:\windows\rundll.exe user.exe,exitwindowsexec'

This Shortcut on clicking will restart Windows immediately without any Warning. To create a Shortcut to Restarting Windows, type the following in the Command Line box:

'c:\windows\rundll.exe user.exe,exitwindows'

This Shortcut on clicking will shut down Windows immediately without any Warning.

Ban Shutdowns : A trick to Play on Lamers

This is a neat trick you can play on that lamer that has a huge ego, in this section I teach you, how to disable the Shut Down option in the Shut Down Dialog Box. This trick involves editing the registry, so please make backups. Launch regedit.exe and go to :

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

In the right pane look for the NoClose Key. If it is not already there then create it by right clicking in the right pane and selecting New > String Value.(Name it NoCloseKey ) Now once you see the NoCloseKey in the right pane, right click on it and select Modify. Then Type 1 in the Value Data Box.

Doing the above on a Win98 system disables the Shut Down option in the Shut Down Dialog Box. But on a Win95 machine if the value of NoCloseKey is set to 1 then click on the Start > Shut Down button displays the following error message:

This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.

You can enable the shut down option by changing the value of NoCloseKey to 0 or simply deleting the particular entry i.e. deleting NoCloseKey.

Instead of performing the above difficult to remember process, simply save the following with an extension of .reg and add it's contents to the registry by double clicking on it.

REGEDIT4

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]

"NoClose"="1"

Disabling Display of Drives in My Computer

This is yet another trick you can play on your geek friend. To disable the display of local or networked drives when you click My Computer go to :

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Now in the right pane create a new DWORD item and name it NoDrives. Now modify it's value and set it to 3FFFFFF (Hexadecimal) Now press F5 to refresh. When you click on My Computer, no drives will be shown. To enable display of drives in My Computer, simply delete this DWORD item. It's .reg file is as follows:

REGEDIT4

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]

"NoDrives"=dword:03ffffff

Take Over the Screen Saver

To activate and deactivate the screen saver whenever you want, goto the following registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ScreenSavers

Now add a new string value and name it Mouse Corners. Edit this new value to -Y-N. Press F5 to refresh the registry. Voila! Now you can activate your screensaver by simply placing the mouse cursor at the top right corner of the screen and if you take the mouse to the bottom left corner of the screen, the screensaver will deactivate.

Pop a banner each time Windows Boots

To pop a banner which can contain any message you want to display just before a user is going to log on, go to the key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WinLogon

Now create a new string Value in the right pane named LegalNoticeCaption and enter the value that you want to see in the Menu Bar. Now create yet another new string value and name it: LegalNoticeText. Modify it and insert the message you want to display each time Windows boots. This can be effectively used to display the company's private policy each time the user logs on to his NT box. It's .reg file would be:

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Winlogon]

"LegalNoticeCaption"="Caption here."

Delete the Tips of the Day to save 5KB

Windows 95 had these tips of the day which appeared on a system running a newly installed Windows OS. These tips of the day are stored in the Windows Registry and consume 5K of space. For those of you who are really concerned about how much free space your hard disk has, I have the perfect trick.

To save 5K go to the following key in Regedit:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Tips

Now simply delete these tricks by selecting and pressing the DEL key.

Change the Default Locations

To change the default drive or path where Windows will look for it's installation files, go to the key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup\SourcePath

Now you can edit as you wish.

Secure your Desktop Icons and Settings

You can save your desktop settings and secure it from your nerdy friend by playing with the registry. Simply launch the Registry Editor go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

In the right pane create a new DWORD Value named NoSaveSettings and modify it's value to 1. Refresh and restart for the settings to get saved.

CLSID Folders Explained

Don't you just hate those stubborn stupid icons that refuse to leave the desktop, like the Network Neighborhood icon. I am sure you want to know how you can delete them. You may say, that is really simple, simply right click on the concerned icon and select Delete. Well not exactly, you see when you right click on these special folders( see entire list below)neither the rename nor the delete option does not appear. To delete these folders, there are two methods, the first one is using the System Policy Editor(Poledit in the Windows installation CD)and the second is using the Registry.

Before we go on, you need to understand what CLSID values are. These folders, like the Control Panel, Inbox, The Microsoft Network, Dial Up Networking etc are system folders. Each system folder has a unique CLSID key or the Class ID which is a 16-byte value which identifies an individual object that points to a corresponding key in the registry.

To delete these system Folders from the desktop simply go to the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Desktop\Namespace{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}

To delete an icon simply delete the 16 byte CLSID value within "NameSpace". The following are the CLSID values of the most commonly used icons:

My Briefcase:{85BBD920-42AO-1069-A2E4-08002B30309D}

Desktop: {00021400-0000-0000-C000-0000000000046}

Control Panel:{21EC2020-3AEA-1069-A2DD-08002B30309D}

Dial-Up-Networking:{992CFFA0-F557-101A-88EC-00DD01CCC48}

Fonts: {BD84B380-8CA2-1069-AB1D-08000948534}

Inbox :{00020D76-0000-0000-C000-000000000046}

My Computer :{20D04FE0-3AEA-1069-A2D8-08002B30309D}

Network Neighborhood:{208D2C60-3AEA-1069-A2D7-O8002B30309D}

Printers :{2227A280-3AEA-1069-A2DE-O8002B30309D}

Recycle Bin :{645FF040-5081-101B-9F08-00AA002F954E}

The Microsoft Network:{00028B00-0000-0000-C000-000000000046}

History: {FF393560-C2A7-11CF-BFF4-444553540000}

Winzip :{E0D79300-84BE-11CE-9641-444553540000}

For example, to delete the Recycle Bin, first note down it's CLSID value, which is: 645FF040-5081-101B-9F08-00AA002F954E. Now go to the Namespace key in the registry and delete the corresponding key.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\Desktop\NameSpace\{645FF040-5081-101B-9F08-00AA002F954E}

Similarly to delete the History folder, delete the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\Desktop\NameSpace\{FBF23B42-E3F0-101B-8488-00AA003E56F8}

Sometimes, you may need to play a trick on your brother or friend, well this one teaches you how to hide all icons from the Desktop. Go to the following registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

In the right pane create a new DWORD value by the name: NoDesktop and set its value to: 1. Reboot and you will find no icons on the desktop.

Till now you simply learnt how to delete the special system folders by deleting a registry key, but the hack would have been better if there was a way of adding the DELETE and RENAME option to the right click context menus of these special folders. You can actually change the right click context menu of any system folder and add any of the following options: RENAME, DELETE, CUT, COPY, PASTE and lots more.

This hack too requires you to know the CLSID value of the system folder whose menu you want to customize. In this section, I have taken up Recycle Bin as the folder whose context menu I am going to edit.

Firstly launch the registry editor and open the following registry key:

HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder.

In Case you want to edit some other folder like say the FONTS folder, then you will open the following key:

HKEY_CLASSES_ROOT\CLSID\{CLSID VALUE HERE}\ShellFolder.

In the right pane there will be a DWORD value names attributes. Now consider the following options:

1. To add the Rename option to the menu, change the value of Attributes to

50 01 00 20

2. To add the Delete option to the menu, change the value of Attributes to

60 01 00 20

3. To add both the Rename & Delete options to the menu, change the value of Attributes to 70,01,00,20

4. Add Copy to the menu, change Attributes to 41 01 00 20

5. Add Cut to the menu, change Attributes to 42 01 00 20

6. Add Copy & Cut to the menu, change Attributes to 43 01 00 20

7. Add Paste to the menu, change Attributes to 44 01 00 20

8. Add Copy & Paste to the menu, change Attributes to 45 01 00 20

9. Add Cut & Paste to the menu, change Attributes to 46 01 00 20

10.Add all Cut, Copy & Paste to the menu, change Attributes to 47 01 00 20

We want to add only the Rename option to the right click context menu of the Recycle Bin, so change the value of attributes to: 50 01 00 20. Press F5 to refresh and then after rebooting you will find that when you right click on the Recycle Bin a RENAME option pops up too.

To reset the default Windows options change the value of Attributes back to

40 01 00 20

The Registry File which one can create for the above process would be something like the below:

REGEDIT4

[HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\Shell-Folder]

"Attributes"=hex:50,01,00,20

To access say the Modem Properties in the Control Panel Folder, the normal procedure is: Click on Start, Click on Settings> Control Panel and then wait for the Control Panel window to pop up and then ultimately click on the Modems icon.

Wouldn't it be lovely if you could shorten the process to: Click on Start> Control Panel>Modems. Yes you can add the Control Panel and also all other Special System Folders directly to the first level Start Menu. Firstly collect the CLSID value of the folder you want to add to the start menu. I want to add Control Panel hence the CLSID value is: 21EC2020-3AEA-1069-A2DD-08002B30309D

Now right click on the Start Button and select Open. Now create a new folder and name it: Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}

NOTE: Do not forget the period after the 'l' in Panel. Similarly all system folders can be added to the Start Menu.(accept My Briefcase, I think)

Deleting System Options from the Start menu

You can actually remove the Find and Run options from the start menu by performing a simple registry hack. Again like always Launch the registry editor and scroll down to the below key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Right-click on the right pane and select New, DWORD Value. Name it NoFind.(To remove the RUN option name it NoRun). Double-click the newly create DWORD to edit it's value and enter 1 as its value. This will disable the FIND option of the Start Menu and will also disable the default Shortcut key(F3 for Find.)

To restore the Run or find command modify the value of the DWORD to 0 or simply Delete the DWORD value.

Fed Up of the boring Old Yellow Folder Icons?[Drive Icons Included]

NOTE: This trick hasn't been tried on Win98.

You can easily change the boring yellow folder icons to your own personalized icons. Simply create a text file and copy the following lines into it:

[.ShellClassInfo]

ICONFILE=Drive:\Path\Icon_name.extension

Save this text file by the name, desktop.ini in the folder, whose icon you want to change. Now to prevent this file from getting deleted change it's attributes to Hidden and Read Only by using the ATTRIB command.

To change the icon of a drive, create a text file containing the following lines:

[Autorun]

ICON=Drive:\Path\Icon_name.extension

Save this file in the root of the drive whose icon you want to change and name it autorun.inf For Example, if you want to change the icon of a floppy, SAVE THE icon in a:\icon_name.ico One can also create a kewl icon for the Hard Disk and create a text file [autorun.inf] and store it in "c:\".

Securing NT

By default, NT 4.0 displays the last person who logged onto the system. This can be considered to be a security threat, especially in the case of those who choose their password to be same as their Username. To disable this bug which actually is a feature, go to the following key in the registry editor:

HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon

Click and select the ReportBookOK item and create a new string value called DontDisplayLastUserName. Modify it and set it's value to 1.

As a system administrator, you can ensure that the passwords chosen by the users are not too lame or too easy to guess. NT has this lovely utility called the User Manager which allows the administrator to set the age limit of the password which forces the users to change the password after a certain number of days. You can also set the minimum length of passwords and prevent users to use passwords which already have been used earlier and also enable account lockouts which will deactivate an account after a specified number of failed login attempts.

When you log on to Win NT, you should disable Password Caching, this ensures Single NT Domain login and also prevents secondary Windows Logon screen.

Simply copy the following lines to a plain text ASCII editor like: Notepad and save it with an extension, .reg

----------------DISABLE.reg-----------------

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Network]

"DisablePwdCaching"=dword:00000001

----------------DISABLE.reg-----------------

To Enable Password Caching use the following .reg file:

--------------Enable.reg-----------------

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Network]

"DisablePwdCaching"=dword:00000000

--------------Enable.reg-----------------

Cleaning Recent Docs Menu and the RUN MRU

The Recent Docs menu can be easily disabled by editing the Registry. To do this go to the following Key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Now in the right pane, create a new DWORD value by the name: NoRecentDocsMenu and set it's value to 1. Restart Explorer to save the changes.

You can also clear the RUN MRU history. All the listings are stored in the key:

HKEY_USERS\.Default\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU

You can delete individual listings or the entire listing. To delete History of Find listings go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Doc Find Spec MRU

and delete.

Customizing the Right Click Context Menu of the Start Menu

When you right click on the start menu, only 3 options pop up: Open, Explore, and Find. You can add your own programs to this pop up menu( which comes up when we right click on it.) Open Regedit and go to the following registry key:

HKEY_CLASSES_ROOT\Directory\Shell

Right click on the shell and create a new Sub Key (You can create a new SubKey by right clicking on the Shell Key and selecting New > Key.). Type in the name of the application you want to add to the start menu. I want to add Notepad to the Start Menu and hence I name this new sub key, Notepad. Now right click on the new registry key that you just created and create yet another new key named Command. Enter the full path of the application, in this case Notepad in the default value of Command in the right

pane. So I Modify the value of the default string value and enter the full pathname of Notepad:

c:\wndows\notepad.exe.

Now press F5 to refresh. Now if you right click on the Start Button you will find a new addition to the Pop Up Menu called Notepad. Clicking on it will launch Notepad.

We can not only add but also remove the existing options in this pop up box.

To delete the Find option, go to the following registry key:

HKEY_CLASSES_ROOT\Directory\Shell\Find

Delete Find. DO NOT delete Open else you will not be able to open any folders in the Start Menu like Programs, Accessories etc.

BMP Thumbnail As Icon

You can actually change the default BMP icon to a thumbnail version of the actual BMP file. To do this simply go to HKCU\Paint.Picture\Default. In the right pane change the value of default to %1. Please note however that this will slow down the display rate in explorer if there are too many BMP thumbnails to display. You can use other icons too, simply enter the pathname.To restore back to the normal change the vale of default back to: C:\Progra~1\Access~1\MSPAINT.EXE,1.

Customizing The Shortcut Arrow

All shortcuts have a tiny black arrow attached to it's icon to distinguish from normal files. This arrow can sometimes be pretty annoying and as a Hacker should know how to change each and everything, here goes another trick. Launch the Registry Editor and go to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\Shell Icons.

Now, on the right pane is a list of icons ( we found out that on some systems, Windows 98 especially, the right pane is blank. Don't worry, just add the value as required ). Find the value 29. If it isn't there, just add it. The value of this string should be C:\Windows\system\shell32.dll, 29 ( which means the 30th icon in shell32.dll - the first one begins with 0 ). Now, we need blank icon to do this. Just create one with white as the whole icon. Go here to learn how to create an icon. Once done just change the value to C:\xxx.ico, 0 where "xxx" is the full path of the icon file and "0" is the icon in it.

Now for some fun. If the blank icon is a bit boring, change it again. You will find that under shell32.dll there is a gear icon, a shared folder ( the hand ) and much more. Experiment for yourself!

Use Perl to Get List or Services Running on your NT box

Internet Explorer Tricks and Tips

Resizable Full Screen Toolbar

The Full Screen option increases the viewable area and makes surfing more enjoyable but sometimes we need the Toolbar but also need to have extra viewing area. Now this hack teaches you how to change the size of the Internet Explorer toolbar. This registry hack is a bit complicated as it involves Binary values, so to make it simple, I have included the following registry file which will enable the resizable option of the Internet Explorer toolbar which was present in the beta version of IE.

REGEDIT4

Making the Internet Explorer & the Explorer Toolbars Fancy

The Internet Explorer toolbar looks pretty simple. Want to make it fancy and kewl? Why not add a background image to it. To do this kewl hack launch the Windows Registry Editor and go to the following key: HKEY_CURRENT_USER\SOFTWARE\Microsoft\ Internet Explorer\Toolbar\.

Now in the right pane create a new String Value and name it BackBitmap and modify it's value to the path of the Bitmap you want to dress it up with by rightclicking on it and choosing Modify. When you reboot the Internet Explorer and the Windows Explorer toolbars will have a new look.

Change Internet Explorer's Caption

Don't like the caption of Internet Explorer caption? Want to change it? Open the registry editor and go to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main.

In the right pane create a new String Value names Window Title (Note the space between Window and Title). Right click on this newly created String Value and select Modify. Type in the new caption you want to be displayed. Restart for the settings to take place.

Now let's move on to some Outlook Express Tricks.

Colorful Background

Don't like the boring background colors of Outlook Express? To change it launch the Windows Registry Editor and scroll down to the

On the left pane, click on ColorCycle or select Edit and Modify in the menu. Now change the value to 1. Close and restart. Now, launch Outlook Express and whenever you open up a New Message, hold down ctrl-shift and tap the z key to scroll to change the background color. Repeat the keystroke to cycle through the colors.

Internet Explorer 5 Hidden Features

Microsoft Internet Explorer 5 has several hidden features which can be controlled using the Windows Registry. Open your registry and scroll down to the following key:

Create a new DWORD value named x(See complete list of values of x below) and modify it's value to 1 to enable it and to 0 to disable it.

NoBrowserClose : Disable the option of closing Internet Explorer.

NoBrowserContextMenu : Disable right-click context menu.

NoBrowserOptions : Disable the Tools / Internet Options menu.

NoBrowserSaveAs : Disable the ability to Save As.

NoFavorites : Disable the Favorites.

NoFileNew : Disable the File / New command.

NoFileOpen : Disable the File / Open command.

NoFindFiles : Disable the Find Files command.

NoSelectDownloadDir : Disable the option of selecting a download directory.

NoTheaterMode : Disable the Full Screen view option.

Hacking Secrets

Almost all system administrators make certain changes and make the system restricted. System Administrators can hide the RUN option, the FIND command, the entire Control Panel, drives in My Computer like D: A: etc. They can even restrict activities of a hacker my disabling or hiding, even the tiniest options or tools.

Most commonly these restrictions are imposed locally and are controlled by the Windows Registry. But sometimes the smart system administrators control the activities of the hacker by imposing restrictions remotely through the main server.

Poledit or Policy Editor is a small kewl tool which is being commonly used by system administrators to alter the settings of a system. This utility is not installed by default by Windows. You need to install in manually from the Windows 98 Installation Kit from the Resource Kit folder. user.dat file that we saw earlier.

The Policy Editor tool imposes restrictions on the user's system by editing the user.dat file which in turn means that it edits the Windows Registry to change the settings. It can be used to control or restrict access to each and every folder and option you could ever think of. It has the power to even restrict access to individual folders, files, the Control Panel, MS DOS, the drives available etc. Sometimes this software does make life really hard for a Hacker. So how can we remove the restrictions imposed by the Policy Editor? Well read ahead to learn more.

You see the Policy Editor is not the only way to restrict a user's activities. As we already know that the Policy Editor edits the Windows Registry(user.dat) file to impose such restrictions. So this in turn would mean that we can directly make changes to the Windows Registry using a .reg file or directly to remove or add restrictions.

Launch Regedit and go to the following Registry Key:

HKEY_CURRENT_USER/Software/Microsoft/CurrentVersion/Policies

Under this key, there will definitely be a key named explorer. Now under this explorer key we can create new DWORD values and modify it's value to 1 in order to impose the restriction. If you want to remove the Restriction, then you can simply delete the respective DWORD values or instead change their values to 0. The following is a list of DWORD values that can be created under the Explorer Key-:

NoDeletePrinter: Disables Deletion of already installed Printers

NoAddPrinter: Disables Addition of new Printers

NoRun : Disables or hides the Run Command

NoSetFolders: Removes Folders from the Settings option on Start Menu (Control Panel, Printers, Taskbar)

NoSetTaskbar: Removes Taskbar system folder from the Settings option on Start Menu

NoFind: Removes the Find Tool (Start >Find)

NoDrives: Hides and does not display any Drives in My Computer

NoNetHood: Hides or removes the Network Neighborhood icon from the desktop

NoDesktop: Hides all items including, file, folders and system folders from the Desktop

NoClose: Disables Shutdown and prevents the user from normally shutting down Windows.

NoSaveSettings: Means to say, 'Don't save settings on exit'

DisableRegistryTools: Disable Registry Editing Tools (If you disable this option, the Windows Registry Editor(regedit.exe) too

will not work.)

NoRecentDocsHistory: Removes Recent Document system folder from the Start Menu (IE 4 and above)

ClearRecentDocsOnExit: Clears the Recent Documents system folder on Exit.

Nolnternetlcon: Removes the Internet (system folder) icon from the Desktop

Under the same key: HKEY_CURRENT_USER/Software/Microsoft/CurrentVersion/Policies you can create new subkeys other than the already existing Explorer key. Now create a new key and name it System. Under this new key, system we can create the following new DWORD values(1 for enabling the particular option and 0 for disabling the particular option):

NODispCPL: Hides Control Panel

NoDispBackgroundPage: Hides Background page.

NoDispScrsavPage: Hides Screen Saver Page

NoDispAppearancePage: Hides Appearance Page

NoDispSettingsPage: Hides Settings Page

NoSecCPL: Disables Password Control Panel

NoPwdPage: Hides Password Change Page

NoAdminPaqe: Hides Remote Administration Page

NoProfilePage: Hides User Profiles Page

NoDevMgrPage: Hides Device Manager Page

NoConfigPage: Hides Hardware Profiles Page

NoFileSysPage: Hides File System Button

NoVirtMemPage: Hides Virtual Memory Button

Similarly, if we create a new subkey named Network, we can add the following DWORD values under it(1 for enabling the particular option and 0 for disabling the particular option):

NoNetSetupSecurityPage: Hides Network Security Page

NoNelSetup: Hides or disables the Network option in the Control Panel

NoNetSetupIDPage: Hides the Identification Page

NoNetSetupSecurityPage: Hides the Access Control Page

NoFileSharingControl: Disables File Sharing Controls

NoPrintSharing: Disables Print Sharing Controls

Similarly, if we create a new subkey named WinOldApp, we can add the following DWORD values under it(1 for enabling the particular option and 0 for disabling the particular option):

Disabled: Disable MS-DOS Prompt

NoRealMode: Disable Single-Mode MS-DOS.

So you see if you have access to the Windows Registry, then you can easily create new DWORD values and set heir value to 1 for enabling the particular option and 0 for disabling the particular option. But Sometimes, access to the Windows Registry is blocked. So what do you do? Go to the Windows Directory and delete either user.dat or system.dat (These 2 files constitute the Windows Registry.) and reboot. As soon as Windows logs in, it will display a Warning Message informing you about an error in the Windows Registry. Simply ignore this Warning Message and Press CTRL+DEL+ALT to get out of this warning message.(Do not press OK) You will find that all restrictions have been removed.

The most kind of restriction found quite commonly is the Specific Folder Restriction, in which users are not allowed access to specific folders, the most common being the Windows folder, or sometimes even access to My Computer is blocked. In effect, you simply cannot seem to access the important kewl files which are needed by you to do remove restrictions. What do you? Well use the RUN command. (START >RUN). But unfortunately a system administrator who is intelligent enough to block access to specific folder, would definitely have blocked access to the RUN command. Again we are stuck.

Windows is supposed to be the most User Friendly Operating System on earth. (At least Microsoft Says so.)

It gives the User an option to do the same thing in various ways. You see the RUN command is only the most convenient option of launching applications, but not the only way. In Windows you can create shortcuts to almost anything from a file, folder to a Web URL. So say your system administrator has blocked access to the c:\windows\system folder and you need to access it. What do you do? Simply create a Shortcut to it. To do this right click anywhere on the desktop and select New > Shortcut. A new window titled Create Shortcut pops up. Type in the path of the restricted folder you wish to access, in this case c:\windows\system. Click Next, Enter the friendly name of the Shortcut and then click Finish. Now you can access the restricted folder by simply double clicking on the shortcut icon. Well that shows how protected and secure *ahem Windows *ahem is.

****************

HACKING TRUTH: Sometimes when you try to delete a file or a folder, Windows displays an error message saying that the file is protected. This simply means that the file is write protected, or in other words the R option is +. Get it? Anyway, you can stop Windows from displaying this error message and straightaway delete this file by changing its attributes to Non Read Only. This can be done by Right Clicking on the file, selecting Properties and then

unselecting the Read Only Option.

***************

There is yet another way of accessing restricted folders. Use see, DOS has a lovely command known as START. Its general syntax is:

START application_path

It does do what it seems to do, start applications. So in you have access to DOS then you can type in the START command to get access to the restricted folder. Now mostly access to DOS too would be blocked. So again you can use the shortcut trick to launch, c:\command.com or c:\windows\command.com. (Command.com is the file which launches MS DOS).

Accessing Restricted Drives.

The problem with most system administrators is that they think that the users or Hackers too are stupid. Almost all system administrators use the Registry Trick (Explained Earlier) to hide all drives in My Computer. So in order to unhide or display all drives, simply delete that particular key.(Refer to beginning of Untold Secrets Section.)

Some systems have the floppy disk disabled through the BIOS. On those systems if the BIOS is protected, you may need to crack the BIOS password. (For that Refer to the Windows Hacking Chapter). Sometimes making drives readable (Removing R +) and then creating Shortcuts to them also helps us to get access to them.

Further Changing your Operating System's Looks by editing .htt files

If you have installed Windows Desktop Update and have the view as Web Page option enabled, you can customise the way the folder looks by selecting View > Customise this folder. Here you can change the background and other things about that particular folder. Well that is pretty lame, right? We hackers already know things as lame as that. Read on for some kewl stuff.

Well, you could also change the default that is stored in a Hidden HTML Template file (I think so..) which is nothing but a HTML document with a .htt extension. This .htt file is found at: %systemroot%\web\folder.htt.

The %systemroot% stands for the drive in which Windows is Installed, which is normally C:

You can edit these .htt files almost just like you edit normal .HTM or .HTML files. Simply open them in an ASCII editor like Notepad. The following is a list of .htt files on your system which control various folders and which can be edited to customise the way various folders look.

controlp.htt Control Panel

printers.htt Printers

mycomp.htt My Computer

safemode.htt Safe Mode

All these files are found in the web folder in %systemfolder%. The folder.htt file has a line:

'Here's a good place to add a few lines of your own"

which is the place where you can add your own A HREF links. These links would then appear in the folder whose folder.htt file you edited. All this might sound really easy and simple, but you see these .htt files do not contain normal HTML code, instead they contain a mixture of HTML and web bots. Hence they can be difficult for newbies to understand.

Well that's it for now, more tricks later, till then goodbye.
Happy Hacking
