We can disable "Set as Desktop background" with one of the following methods:
For Windows XP Professional Edition:
---------------
1. Click Start and then Run. Type "gpedit.msc" without quotes and press Enter.
2. In Group Policy Editor, go to
Local Computer Policy -> User Configuration -> Administrative Templates -> Control Panel -> Display
3. Locate a setting named "Prevent Changing Wallpaper". Double click to open it.
4. Select Enable and click OK.
For Windows XP Home Edition
---------------
1. Click Start and then Run. Type "regedit" without quotes and press Enter.
2. Navigate to the following branch:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\ActiveDesktop
3. Please check if there is the value: NoChangingWallPaper. If so, please double click it and then change its value to 1
Note: If the value name doesn’t exist, we need to create it manually (Right click the blank space and choose New -> DWORD value)
For your reference, you can also copy the following content to a Text Document, and then save it as an Reg file (such as NoChangingWallPaper.reg). Then we can double click the reg file to import the content to registry:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\Curr entVersion\Policies\ActiveDesktop]
"NoChangingWallPaper"=dword:00000001
