Prevent your computer from "not responding"
 

open registry

go to: HKEY_CURRENT_USER\Control Panel\Desktop

locate DWORD value

"WaitToKillAppTimeout"

default value might be

"WaitToKillAppTimeout"="20000"

this value represents the time(in milisecond) taken by window to end program when it is not
responding.

change it to 0

and prevent your computer by hanging.
