No, there is no easy way of preventing the user from killing your process with task manager. You could set it to a critical process, causing a BSOD upon termination (couple of lines of code).

But you are "white hat" so why even do this? It seems like something that does not need to happen.

Since it is a white hat program instead of re-spawning the process if killed, maybe log the event, time, logged in user, system state, open windows, and email the parent, and perhaps even force a log off or lock a screensaver. Then they can discipline their kids so they will not close the program again.

This would required either a second monitoring process, or an injected dll, or remote thread. The monitoring process is more whitehat and will cause less issues in a production environment for your purpose.

Just my thoughts
