Register-WmiEvent

Short description
Subscribes to a Windows Management Instrumentation (WMI) event.

Syntax


Description
The Register-WmiEvent cmdlet subscribes to WMI events on the local computer or on a remote computer.


When the subscribed WMI event is raised, it is added to the event queue in your local session even if the event occurs 
on a remote computer. To get events in the event queue, use the Get-Event cmdlet.


You can use the parameters of Register-WmiEvent to subscribe to events on remote computers and to specify the property 
values of the events that can help you to identify the event in the queue. You can also use the Action parameter to 
specify actions to take when a subscribed event is raised.


When you subscribe to an event, an event subscriber is added to your session. To get the event subscribers in the 
session, use the Get-EventSubscriber cmdlet. To cancel the subscription, use the Unregister-Event cmdlet, which 
deletes the event subscriber from the session.


New CIM cmdlets, introduced Windows PowerShell 3.0, perform the same tasks as the WMI cmdlets. The CIM cmdlets comply 
with WS-Management (WSMan) standards and with the Common Information Model (CIM) standard, which enables the cmdlets 
to use the same techniques to manage Windows computers and those running other operating systems. Instead of using 
Register-WmiEvent, consider using the Register-CimIndicationEvent cmdlet.
