Windows XP Shutdown too slow, fix it to shutdown instantly

1. Open Start >> Run and type regedit and press enter
2. Now navigate to ‘HKEY_CURRENT_USER\Control Panel\Desktop\’In this entry, you will see a registry key named WaitToKillAppTimeout .

Double click on it and set its value to 1000 , this value is the time in milliseconds for which the windows waits before all the processes and services are closed.
This way you have set it to 1 second.
Not only this, there are some other registry settings set by default due to which Windows XP will prompt the user for input if there are one or more applications still not closed or not responding. This increases the shutdown time due to no response from the user.
So, you should also change that registry key settings value.
3. Navigate to ‘HKEY_CURRENT_USER\Control Panel\Desktop’
window.google_render_ad();
Double click on the registry key ‘AutoEndTasks.’ and set its value to 1
4. That is all, Trouble Fixed.
Now restart your system, you will see a considerable reduction in the shutdown time this time.
