Cannot Change the Desktop Wallpaper

SUMMARY: If you cannot change your Windows XP desktop wallpaper because all options are disabled, view this tip.
A virus, certain spyware, a malformed registry, or other circumstances can transpire making it impossible for you to change the Windows XP desktop wallpaper. When you try to modify the background picture, neither the list of images nor the "Browse" button is clickable.

If this happens, you can perform a registry tweak to restore the functionality. Note you must be an Administrator to perform this tip.

NOTE: Be careful what you are doing when modifying the registry as you can harm your computer or keep it from booting!

1. Run "Regedit".
2. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ Windows\CurrentVersion\policies
3. If you see a folder (key) "ActiveDesktop" select it. If not, make a new key and label it "ActiveDesktop".
4. If you see "NoChangingWallPaper", double-click the DWORD value and set it to "0". Otherwise, you need to create a new DWORD value of "NoChangingWallPaper" and set it to "0".
5. Try changing your wallpaper. If this fix doesn't solve the problem, you may also need to make the above registry changes at location: HKEY_CURRENT_USER\Software\Microsoft\ Windows\CurrentVersion\Policies .
