Well ! guys, My problem is, some of my friends come over to my place and use my computer to chat over the internet using Yahoo Messenger, and they use the "regedit.exe" from the run dialog. They basically use the regedit to look for profiles of other chatters. What i want is to disable the regedit command temporarily but i also do not want to disable this command by using any freeware tools or any other software. Can I disable this command from the Window XP itself ? Please help.
