Re: Limit non-administrator users
Something I installed in one of my client's Cyber Cafe is a program called Deep Freeze by Faronics, although not free. I install that and set it up, then I don't even worry about any other security because every time the computer reboots, it's like re-imaging the computer. If you need to install an update, set it to reboot "thawed". It will be able to take changes in thawed mode, and when you are done, reboot to frozen mode. You could literally format the C: drive and then reboot and it would be back to normal.
