I have a simple WinForms application that runs in the system tray. Is it possible to password protect the program from closing if a user tries to close it from task manager?
Ideally I want to keep a user from closing the process but if windows is restarted, I want it to close without being prompted. Much like antivirus programs.
If a user has the correct permissions they will be able to kill your process from the Task Manager.
That said as @fujiFX mentions in his comment the FormClosing event is a good start and better than nothing.
