Win8.1 new changes: completely turn off the Metro application, you need to wait for the magnetic stickers to turn over

        Win8 users know that using the down gesture (that is, selecting the app and pulling it down from the top of the screen to the bottom of the screen to close the app) can completely shut down the app. But in the Win8.1 preview, Microsoft made changes; applications that use the down gesture to close seem to be kept in the system process?
Originally, to completely close the application in the Win8.1 preview, you need to wait a little longer than Win8. In Windows 8.1, use the down gesture to pull the app to the bottom of the screen. At this point, you need to stabilize the tile waiting for the app to become the logo in the Windows Store (or, you need to wait for the app to be turned over). In order to completely shut it down.

Anyway, Microsoft introduced a new application memory management mechanism in Win8, the application will be suspended in a dormant state, in order to quickly wake up again. By default, the Metro application only suspends and does not close. When the key point of the memory capacity limit is encountered, the system will release the memory by closing the Metro application.
