    You can't. That's sort of the whole point of it. – James Thorpe Feb 09 '16 at 15:00

  • Keeping a user for opening Task Manager should be done via login permissions. – juharr Feb 09 '16 at 15:18

That is a special keystroke that is impossible to hook into for security purposes.

  • You can hook the combination of keys. Just store keydown or key up until you get control+alt+del – Jacobr365 Feb 09 '16 at 15:01

    Try it. You can't stop the user from bringing up the task manager this way if they want to. – Lou Franco Feb 09 '16 at 15:02
  • Yea, I don't know about interacting with the task manager, but you can get your program to be alerted to the fact that the task manager was opened with the key shortcut. – Jacobr365 Feb 09 '16 at 15:03
  • People who down voted the question were maybe thinking that I was trying to make any kind of virus or something like that. but no, I was just willing to know if these kind of functionalities are possible or not. Thanks for the answer @LouFranco – Jamshaid K. Apr 05 '17 at 20:12
