How to improve shutdown time? or how to quick shutdown my system?
I am having a tweak which can improve shutdown time of your system or it reduces the time xp waits before automatically closing any running programs when you give it the command to shutdown.
Well following steps will clearly explains you How to improve shutdown time of windows xp.

1)Click on Start and Select Run.
2)Type “REGEDIT” without quotes in RUN.
3)Now find this registry “HKEY_CURRENT_USER\Control Panel\Desktop\”
4)select “WaitToKillAppTimeout”
5)Right click on the selected registry and select “Modify”
6)Change the value to ‘1000′
7)Now click “OK”
8)Now select ‘HungAppTimeout’
9)Change this to “1000″
10)Now click OK.

Checkout one more method which is simple and some what trick then first method.
1)After opening this registry key “HKEY_CURRENT_USER\Control Panel\Desktop\” find AutoEndTasks.
2)Default value always ZERO. change default value to 1. Your work has done completely.Further more you can reduce the time it takes for Windows to issue kill directive to all active/hung applications. While doing this method make sure constraint only exists in that HungAppTimeout is greater than WaitToKillAppTimeout. now change the value of WaitToKillAppTimeout to say 3500 (since default value for HungAppTimeout 5000 and for WaitToKillAppTimeout is 20000)…..
