If your computer takes too long to shutdown, then a running service or application probably takes a long time to close and prevents your system to shutdown. During this behavior, Windows wait some time for the service (or application) to respond and after that time, notify the user that the service is not stopped and prompts him what to do. Then the user has to decide either to stop (End Task) the service or to wait until the service closes automatically.
This tutorial will show you how to speed up Shutdown time in Windows Operating Systems, by decreasing the time that Windows wait before prompting the user what to do with the unresponsive running application(s) or service(s). To accomplish this task you have to decrease the WaitToKillServiceTimeout value found inside Windows Registry. The WaitToKillServiceTimeout value tells Windows how long to wait before proceeding to prompt the user about the unresponsive applications or services.
