i have two teenage kids that love fiddle with there computer eg. open control panel / folder options/ veiw/ show hidden files and folders then go and delete the ntldr system file

for some reason, then they blame each other "it wasnt me"
i was wondring if there is a program that will add restriction to there accounts eg.
no control pannel
no c:/ "system drive"
no my network places or no changing network connection
no changing there start menu
so its kind of like a internet cafe I understand that to make changes you have to use regedit
but i dont want to break it ether
so if you know any great apps that will give a GUI makin it easier, savin me alot of hair^
ps DNT delete the ntldr system file untill you say: GOODBYE
