As a remember as a teenager I wrote a program that would constantly call the beep function (read: loud squeals from your motherboard speaker, if you had one, and not affected by volume controls so you couldn’t turn it off easily) and then that program would use the Win32 APIs to also poll for any task manager windows you might launch and minimize them immediately so that you couldn’t kill the process. I sent beep.exe to some of my friends on AIM at the time and they ran it (it was a simpler time) and were not amused- even after I told them they could just restart their computer to make it stop. (I had a version that added itself to the registry to auto run at startup, but even my teenage self thought that was a bit too far).
