### DECIDE WHICH EVENTS SHOULD BE WATCHED 
 
#The Register-ObjectEvent cmdlet subscribes to events that are generated by .NET objects on the local computer or on a remote computer.
#When the subscribed event is raised, it is added to the event queue in your session. To get events in the event queue, use the Get-Event cmdlet.
