Are you tired of your Windows computer taking forever to shut down? Then you should try the following Registry tweaks that will help you shut down your computer quickly. Some programs have a preset shut down time takes too long to shut down.
With Windows computer, we have plenty of problems -- starting the computer, running the computer and shutting down the computer. We saw how to start up the computer quickly in an earlier article, and this article will help you how to shut it down quickly.
The computer shut-down takes a longer time because some programs take more time to quit. provides some great tips that will help solve this problem by adjusting the Registry tweaks. I just did a few of them and it works great.
Follow these steps:
1.) Open the Registry Editor (Vista: Press the Windows key, type regedit, and press Enter. In XP: Click Start --> Run then type regedit --> Press Enter.
2.) Click HKEY_CURRENT_USER --> Click Control Panel --> Click desktop (or Desktop) --> Double-click WaitToKillAppTimeout
3.) Change the change the value data (measured in milliseconds) to 1000 (or more if you want other programs to take more time to close).
4.) Close Registry Editor.
WaitToKillAppTimeout, the Windows Registry key that sets the delay before killing applications at shutdown
There is another setting you can make that forces hung applications to close. They just run on the background and take far too much time to quit. To adjust this setting do the same as above except in step 3, instead of “WaitToKillAppTimeout” double-click “HungAppTimeOut” and change the data value to 2000 (milliseconds).
If you have more than one user in the computer, you can make a universal change by doing the following:
Change the value data of WaitToKillAppTimeout and HungAppTimeout in HKEY_USERS/.DEFAULT/Control Panel/Desktop key to apply the changes to all users on the system.
There are few more tips in the main article here, but I just did the above two settings, and it closes very quickly. Before it took more than 3 minutes to close, and now it takes less than a minute.
Before you make these changes, create a restore point, go to to All Programs --> Accessories --> System Tools --> System Restore --> Create a Restore point (sets the time and date).
In case something happens later then you can always go back to this restore point before you installed this program. You should always do this whenever you install a new program.
