Super fast shut down :-

if u want to shutdown ur pc faster or slower:

1- start-->run-->regedit
when u start run and then write regedit

2- +HKEY_LOCAL_MACHINE
+SYSTEM
+CurrentControlSet
Control

left kick on control and u will find WaitToKillServiceTimeout.
dobbel kick on WaitToKillServiceTimeout.
in WaitToKillServiceTimeout its 20000 it means 20 secunds...if u want to shudown windos faster then get the numbers smaller, like 10000 or 5000 (10 sec or 5 sec) or if u want to shutdown longer writ 50000 (50sec).
