Unregister-Event
Cancels an event subscription. PowerShell reference
From the PowerShell reference 5 parameters
What it does
Cancels an event subscription. The Unregister-Event cmdlet cancels an event subscription that was created by using the Register-EngineEvent, Register-ObjectEvent, or Register-WmiEvent cmdlet. When an event subscription is canceled, the event subscriber is deleted from the session and the subscribed events are no longer added to the event queue. When you cancel a subscription to an event created by using the New-Event cmdlet, the new event is also deleted from the session. Unregister-Event does not delete events from the event queue. To delete events, use the Remove-Event cmdlet.
