Shorten the waiting time before closing the application and Process
Similar to the waiting time before closing the service, Windows Vista waits for the application or process before it forcibly closes the application and process.
The time when you close the service on your own. Windows will force stop the service only when the time limit is exceeded.
Therefore, shortening the default application shutdown or waiting time can also speed up the shutdown of Windows 7.
The setting method is similar to the above. In the registry, find the following branch: HKEY_CURRENT_USER \ Control Panel \ Desktop.
Double-click "waittokillapptimeout" in the right panel and change its value from the default 20000 (unit: milliseconds) to a smaller 5000 or 1000,
In this way, if Windows does not receive an application or close a signal after sending a shutdown command for 5 seconds or 1 second, a warning will pop up and ask the user whether to forcibly stop the application.
