Remarks

WSUS uses subscription events to generate synchronization history. The synchronization history is lost when subscription events are removed. Events are removed based on the ServerEventExpirationTime configuration setting.

To retrieve all synchronization history, call GetSynchronizationHistory.

To retrieve synchronization and subscription events, call GetEventHistory.
