I need some software for Windows XP. It is a bit like school software, as I want it to not allow you to change any settings from you desktop background to the start menu. Is there any software or hardware I can use. Also there is 1 PC and 1 Laptop. Is there any way making a background change on the desktop and have it also change on the Laptop. Upgrading both to Win 7 Home. Lappy runs Vista.
