One of the changes introduced in Windows 8.1 is how an application closes: either close it as on Windows 8 (in this case it remains active, “pause” mode), or we close it permanently. Unleash hardware resources with this simple trick to perform.
Edit: Article updated following comments from our readers.
To do this, position your mouse cursor at the top of the application. Your cursor then changes in hand.
Click and hold the pressed-click pulling down the window.
The application will be reduced. Do not release the click, wait a few seconds until the application performs a rotation on itself, then let go.
Now the application is permanently closed.
A convenient option completely hidden from Windows 8.1 users.
