How to Backup Registry??

1. Click on Start and then Run….
2.In the text box in the Run window, type regedit and click OK. This will open the Registry Editor program.
3.Navigate to the very top of the registry key branches until you reach Computer.
4.Highlight Computer by clicking on it once.
5.From the Registry Editor menu, choose File and then Export….
6.In the Export Registry File window that appears, choose a location to save the file in.
Note: I recommend choosing your desktop or the C:\ drive. Both are very easy to access if you run into problems later and need to use the file.
7.Locate the File name: text field and enter a name for the backup file.
Note: This name is for you to remember what the exported registry file is for. Since you're backing up the entire Windows XP Registry, I would recommend calling this file Registry Backup or something like that.
8.Click the Save button.
A Registration File with an REG file extension will be created in the location you chose in Step 6 and with the file name you chose in Step 7. Continuing the example from the last step, the file would be named Registry Backup.reg.
9.You can now make as many changes to any area of the registry that you want.
10.If after making your registry changes, you realize that they did not give you the results you were looking for, you can simply restore the entire Windows XP registry back to the point at which you backed it up.

Disabling My Computer

Disabling My ComputerIn 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.

CHANGING DOS BACKGROUND

To Change a DOS background.

• Open your registry --> press win+r and type regedit --> hit enter.
• goto
  [HKEY_CURRENT_USER\Software\Microsoft\Command Processor]
• You'll find "DefaultColor"
• You can replace it's value with a two-digit hexadecimal number, in which the first digit selects a background color and the second a foreground color.

The hexadecimal codes are:
Hexadecimal_value Color

• 0 Black
• 1 Blue
• 2 Green
• 3 Aqua
• 4 Red
• 5 Purple
• 6 Yellow
• 7 White
• 8 Gray
• 9 Light Blue
• A Light Green
• B Light Aqua
• C Light Red
• D Light Purple
• E Light Yellow
• F Bright White
  Sample: A value of F0, for example, would give black text on a white background

To remove shortcut icon arrows.

Speed Up Shutdown Time for WinXP

XP clear your paging file (pagefile.sys) of its contents whenever you shut down for security reasons. Your paging file is used to store temporary files and data, sensitive information, such as unencrypted passwords etc.
So if extreme security isn't required, then shut down XP without clearing your paging file by :-
1. Run the Registry Editor ( type regedit in Run and enter)
2. Go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
3. Change the value of ClearPageFileAtShutdown to 0.
4.Close the Registry and restart your computer.
Now on while turning off XP , the paging file won't be cleared, and shut down will be more quickly.
