User control

My family likes playing games on my computer because it's pretty much the only one capable of playing anything good. As it is, I only let 'em play when I'm around to make sure they don't go exploring. Is there any way I can severely limit what they have access to so I don't have to babysit them? I want pretty much a blanket "you can't do jack shit except using these shortcuts to games I have installed," so they don't go off and find my pronz.

Help?
Thanks.

easy way: Google "kiosk software" because some of that stuff really limits what users can do

harder way: google "Group policy editor", NTFS access restrictions, software restriction policies etc.

good fun, and it makes you leanr a lot about the OS.
