Edit Registry to Activate Windows

hello,

Can anybody please suggest me how to edit registry to activate Windows ?

Any suggestions or useful ideas will be appreciated....

First, you must do is making a copy of the registry. If any problem arises, this will let you to restore your initial settings .

Next, you must disable the attributes of the files system.dat and user.dat

Finally, run the program "c:\windows\regedit.exe"

Now, you can start modifying the keys that you want to edit.

For Windows XP,

• Start > Run > type %SystemRoot%\System32\Restore\Rstrui.exe, > click OK.
• On the Welcome to System Restore page, click Restore my computer to an earlier time (if it is not already selected), and then click Next .
• On the Select a Restore Point page, click the system checkpoint. In the On this list select the restore point area, click an entry that is named "Guided Help (Registry Backup)," and then click Next. If a System Restore message appears that lists configuration changes that System Restore will make, click OK.
• On the Confirm Restore Point Selection page, click Next. System Restore restores the previous Windows XP configuration and then restarts the computer.
• Log on to the computer. When the System Restore confirmation page appears, click OK.

In Windows operating system, in the registry editor (regedit.exe) you will see 6 main branches:

1. HKEY_CLASSES_ROOT (called HKCR): Contains all file associations; the names of the first keys listed within it correspond to the file extensions in question.
2. Shown lower down on the tree are keys which correspond to the names of file types, and their attributes:
   
   • The default icon (DefaultIcon)
   • The associated action (shell): open, run, etc.
   
   
   
3. HKEY_CURRENT_USER (called HKCU): Defines settings for the current user, and is divided into six sub-categories:
   
   • control panel: for the control panel
   • software: for software that has been installed
   • AppEvents: for system sounds (the beep or boop when you click on something)
   • keyboard layout: for keyboard settings
   • Remote Access: for remote access over a network
   • Network: Network configuration
   
   
   
4. HKEY_LOCAL_MACHINE (called HKLM): Contains all information related to your machine:
   
   • hardware: for the processor and motherboard
   • enum: for hardware (peripheral devices, etc.)
   • network: for networking and the Internet
   • software: for software configurations shared by all users
   
   
   
5. HKEY_USERS (called HKU): Contains separate settings for each user
   
   
6. HKEY_CURRENT_CONFIG (called HKCC): This is a shortcut to the configuration currently being used in HKLM\Config. It contains settings for the current configuration of the computer.
   
   
7. HKEY_DYN_DATA (called HKDD): This is a shortcut to the components currently being used only in RAM in HKLM\Config (volatile information: exists only temporarily, until the system is reinitialised).

I hope this information heps you...
