A[n] program is a set of computer instructions.
I'm not sure why you would need to. An unresponsive program should not effect the integrity of the system to require a reboot.
If an unresponsive program is being particular persistent and won't exit, CTRL + ALT + DEL then Task Manager, and clicking on the program in the "Processes" tab and clicking "End Task" is a reliable way to get rid of it.
Im not sure but the person above is right x :)))
