How to Reduce Shut Down Time: Windows 7 tweak

This is a tweak with which you can reduce the time taken by your machine to shut down.
Now, the time taken by a machine to shut down depends, to a certain extent, on how fast it can stop the running processes. That is why it takes more time when a process is 'hanged' or is not responding.
This tweak will show you how to adjust the "Wait to Kill"  time, the time Windows 7 waits for programs to save data and close before shutting down.
In the start menu, type 'Run' or simply press win+R to open the Run option .
Open the Registry Editor by entering 'regedit'.
In the registry editor, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

In the right pane, right click on WaitToKillServiceTimeout and click on Modify
Type in a number between 1000 to 20000 [1-20 seconds]
The default value is 12000.
Try out different values and adjust the value in such a way that it is minimum as well as optimal for all the programs to close properly.
