There is a blue screen that appears when you press ctrl-alt-del on windows 7 or vista. I figured out how to disable the taskmanager but users can still shutdown the machine.
How can I prevent them from being able to do this?

Because it is the login system of Windows that traps the CTRL-ALT-DEL combination (and so it is not accessible to user applications), you will need to change the system's keyboard scancode map to ignore at least one of those keys.
