How can i disable ctrl alt delete in vista using visual basic?
You may want to think about creating a virtual desktop that spawns when the test is started. Just spawn the test program alone on that desktop and even if they were to hit C+A+D it would only appear on the default desktop which would be unavailable to them. Setup your own super secret Hotkey combination to get back to the deafult desktop. This will also help you lock out most users from even attempting to change anything.





Check out this section for more information on setting it up.

Vista creates a desktop for its I-dunno-what-that-is-calls.


You can try it with the demo program here:

Reply:It should be noted that it is physically impossible to disable the Ctrl+Alt+Delete shortcut as only the kernel recognises it. While you can disguise the computer so the task manager fails to come up (which, it has to be said, is more of a bug than a feature), an experienced user could bypass this if they really wanted to. Basically, never assume security by obscurity, and put in some fallback measures to prevent misuse (e.g. firewalling port 80).
