O.K. I have been using XP for a while now and having a great time of it. Really like the setting and security. Had to re-install because I put in a bigger hard drive. Install went well, no problems. Set up the other users accounts and groups and when I set the reg key to hide the conrol panel it didn't work. I am using XP pro and using the same reg key that I used and worked last time but now XP is being a pain about it? Any suggestions?
