Ghacks shows you how to terminate apps in Windows 8.1

Windows 8 users who are running apps from time to time on their system know that they can be closed completely by moving the mouse cursor to the top of the page, holding the left mouse button down and dragging the app to the bottom of the screen. Once released, it is closed and its process is no longer running on Windows which you can check by opening the Windows Task Manager.

The second option that you have is to use the close option that is displayed in the left Charms Bar.

If you have updated your system to Windows 8.1 Preview or installed the system anew, you may have noticed that both options are no longer working. While dragging the app to the bottom of the screen closes it, it is not terminating it anymore from the task manager.
