ok, i've looked all over, so please don't tell me to read existing msgs... I'm tryin to lock down a system, i've killed everything in the startmenu except help and 2 shortcuts that the user needs to programs, the desktop and nethood are gone, and the nodrives all is set, i have the verify logon setup so the can't cancel, but they can still right click to delete stuff and add shortcuts, i need to find a way to disable right clicking on one user and not the other, i know its possible just because on foolproof it can grey out right clicks... any help would be appreciated.
PS i'm trying not to use any software, just registry stuff
