My first C++ app for a client was leaking so much memory that Windows kept crashing too.
So I had to press Ctrl-Alt-Del every few runs.
But the laptop running the app was enclosed in a box, so the keyboard was inaccessible.
My hack was to set up an Arduino, a push button outside the box and a wire. Asked the steward to push the button every three people trying the system. So the Arduino sends Ctrl-Alt-Del and the app was running again.

The client was happy :)
