+### BackgroundAppUpdate
+
+Enable or disable **automatic** application update **in the background**, when the application is not running.
+
+If set to true, application updates may be installed (without user approval) in the background, even when the application is not running. The operating system might still require approval.
+
+If set to false, the application will not try to install updates when the application is not running.
+
+If you have disabled updates via `DisableAppUpdate` or disabled automatic updates via `AppUpdateAuto`, this policy has no effect.
