Improve shutdown time

Close apps automatically & quickly at shutdown tip:

Open Registry by going to START-RUN and typing REGEDIT. Navigate to HKEY_CURRENT_USER\CONTROL PANEL\DESKTOP and look for AutoEndTasks. On my computer default value is 0. Change it to 1. Thats all. Further more you can reduce the time it takes for Windows to issue kill directive to all active/hung applications.
In doing this only constraint that you should make sure exists is that "Hung App Timeout" is greater than "Wait To KillApp Timeout". Change the values of "Wait To Kill App Timeout" to say 3500 (since default value for "Hung App Timeout" 5000 and for Wait To Kill App Timeout" is 20000)
