Fields

Name Value Description
Abort 0

The background task was canceled by the application. This can happen for one of the following four reasons:

  • The task is considered an idle task. This means that the background task is still running, but without doing anything – for example, a JavaScript task that does not call the close() function.
  • The background task uses the MaintenanceTrigger and the system transitions to DC (battery power).
  • The app unregisters the background task, in which case the task is cancelled if it is currently running.
  • The app that registered the background task is uninstalled while the task is running.
Terminating 1

The background task was canceled because the application is about to be terminated due to system policy. The application should save any state that will be needed when the application restarts.

LoggingOff 2

The background task was canceled because the user has logged off the system.

ServicingUpdate 3

The background task was canceled because the application was updated.

IdleTask 4

The background task was canceled because it was active, but not doing any work.

Uninstall 5

The background task was canceled because the application was uninstalled.

ConditionLoss 6

The background task was canceled because one or more of its required conditions is no longer met.

SystemPolicy 7

The background task was cancelled because of system policy.

QuietHoursEntered 8

Note

QuietHoursEntered is no longer available for use as of Windows 10.

ExecutionTimeExceeded 9
