How to Auto End Tasks to Enable a Proper Shutdown

This reg file automatically ends tasks and timeouts that prevent programs from shutting down and clears the Paging File on Exit.
Copy the following (everything in the box) into notepad:

QUOTE
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
"ClearPageFileAtShutdown"=dword:00000001

[HKEY_USERS\.DEFAULT\Control Panel\Desktop]
"AutoEndTasks"="1"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control]
"WaitToKillServiceTimeout"="1000"

Now Save the file as shutdown.reg
Double click the file to import into your registry.
It maybe possible that ur Antivirus detects this script as malicious but it is not harmful anyway.
