Thanks to everyone for your feedback and the advice on symantec Ghost. Right now i have been toiling for 3 weeks trying to get this security just right. It is a college and the semester is about up so you know i am rush rush. I put some of the workstation back and guess what one of the desktop wallpaper was changed. I am using regedit for restriction and still trying to implement the kix script. What went wrong in the wallpaper. I used NoChangingWallpaper in HKEY_CURRENT_USER SOFTWARE/MICROSOFT/WINDOWS/POLICIES/EXPLORER
This is happening when the students go to the internet and set pictures as wallpaper.
Help me please.
