I used this google to find this.
There are many discussions about this, but you can see in this one there are many "NO! NEIN! NON! NIX! NJET! OXI!" words you can use.
I have a new PC and it comes with the WinXP Home edition. I would like to know how can I block the wallpaper change. With the WinXP Pro I know how to do it. Through the Group Policy. But with this version I could not find the Group Policy and find no way to it. Is there any one can help me!
