Remarks

This table provides more detail about when you'll see each of these states and what your app should do in response.

State When this state is seen What your app should do
NotRunning The user first activates the app after: 1) installing the app from the Store; 2) clicking End task in Task Manager while the app is running; 3) rebooting the computer; 4) logging off and back on.
The user closes the app through the close gesture or Alt+F4 and activates it within about 10 seconds of closing it.		 Display its initial UI and perform initialization tasks.
Running The app is activated through a secondary tile or one of the activation contracts and extensions while it is running. Respond to the activation event as appropriate.
Suspended The app is activated through a secondary tile or one of the activation contracts and extensions while Windows is suspending it or after Windows has suspended it. Respond to the activation event as appropriate.
Terminated Windows successfully suspends the app and then it is terminated. For example, Windows can terminate a suspended app if the system is running low on resources. Some apps, such as games, can be pretty resource intensive. Restore itself to the way the user left it, rather than starting fresh. Use data saved during app suspension. Refresh content or network connections that may have become stale.
ClosedByUser The user closes the app through the close gesture or Alt+F4 and takes longer than 10 seconds to activate the app again. Restore itself to the way the user left it, rather than starting fresh. Use data saved during app suspension. Refresh content or network connections that may have become stale.

Windows 8

In Windows 8, when the State is ClosedByUser, display the app's initial UI and perform initialization tasks, rather than restoring its previous state. If your Windows 8 app depends on the Windows 8 ClosedByUser behavior, you can enable it when you upgrade it to Windows 8.1 or later by setting the Windows.UI.ViewManagement.ApplicationView.TerminateAppOnFinalViewClose property to true.

Windows Phone 8

On Windows Phone, only NotRunning and Suspended are supported.
