Features of the Windows Active Desktop can be selectively controlled by modifying options in the Windows registry.

To do this,  follow the next steps:

1. Open the Registry Editor click on the Start button on your taskbar, then click on Run and type "regedit" and click on OK to start the regedit utility.
    
2. Expand HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ActiveDesktop (see picture 1).

   • NoChangingWallpaper - Disable the ability to change wallpapers.
   • NoComponents - Disable components.
   • NoAddingComponents - Disable the ability to add components.
   • NoDeletingComponents - Disable the ability to delete components.
   • NoEditingComponents - Disable the ability to edit components.
   • NoCloseDragDropBands
   • NoMovingBands - retrict adjustments to desktop toolbars
   • NoHTMLWallPaper - only allow bitmaps (BMP) as wallpaper
      
4. The modifications you made will be in effect after you reboot your PC.
