Sometimes it seems like it takes forever for your computer to shut down. If, in fact, it really DOES take forever to shut down, this registry tweak will speed up the process by shortening the interval that Windows waits for services and programs to close themselves before force-closing them.
Start regedit from the Search box on the Start Menu, and navigate to: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl. Find the WaitToKillServiceTimeout key in the right column, double click on it to edit and change the interval from 12000 to 2000, or from 12 seconds to 2 seconds.
This should help speed up the shut down process for you. And thanks to eSupport.com for this idea.Share
