Interesting, I didn't know you could set it up like that. I guess because I always log in as myself, and I'm an administrator on my XP machine.DirtyMike said:Actually on win XP. if you follow the recomended way to setup your users, you will have to have the Main users PW to be able to install anything. Thats how mine is set, Turn on the machine, it boots up, Its duel OS so i have to select my OS,<One for gaming one for all other> Then i select what user i want to be in and enter ther PW. If your logged into any other user than teh Main, it wont even let you start the Install program. From there you still have to retype the PW. So in reality Mac and PC are only as secure as teh operator wants them to be.
