NS_S_DRM_MONITOR_CANCELLED

Windows Media DRM license monitoring was cancelled

NS_S_DRM_MONITOR_CANCELLED is HRESULT 862022 (0x000D2746) from Windows Media. AllStat describes it as “Status message: License monitoring has been cancelled.” In the Windows Media Player, Windows Media Format, DRM, or Media Foundation state machine, the value reports a nonfailure state that must not be collapsed into plain S_OK.

This result is actionable completion information and may require waiting, reconciliation, fallback, or user disclosure.

Where the status is encountered

  • Windows Media Player library, playlist, store, or UI plug-in callbacks; capture the exact API, object, and phase because the same numeric success severity does not define the state by itself.
  • Windows Media Format source, writer, DRM, publishing-point, or installation operations;
  • Media Foundation topology activation and remote-component setup;

Keep it attached to the operation that returned it. Interpreting it outside that API contract can turn a normal continuation or partial result into an incorrect retry or false completion.

What must be true before accepting it

Verify that the cancellation owner is known and monitoring resources and callbacks are fully detached. That proof prevents usable partial state from being confused with full completion.

Also confirm that returned outputs belong to the current operation generation and were not inherited from an earlier attempt.

Correct handling and recovery

Stop future monitor callbacks, reconcile any license changes already observed, and restart monitoring only through a new explicit request.

Before repeating work after it, reconcile side effects and prove that the next attempt is idempotent.

Difference from nearby results

This status ends monitoring; it does not revoke an acquired license or indicate a DRM failure.

The distinction around it should be visible in control flow, telemetry classification, and user messaging.

Practical scenario

A user signs out while license monitoring is active. The client cancels the monitor, waits for callback quiescence, and closes the profile safely.
