PowerShell 2.0: One Cmdlet at a Time #99 Unregister-Event

Continuing the series looking at new cmdlets available in PowerShell 2.0. This time we look at the Unregister-Event cmdlet.

What can I do with it?

Clear an event subscription.

Example:

Use Get-EventSubscriber to retrive details of current events. Clear the event with subscription id 1 and Get-EventSubscriber again to confirm that it has been removed.

Get-EventSubscriber
Unregister-Event -SubscriptionId 1
Get-EventSubscriber

You will see that the event subscription has been cleared.

How could I have done this in PowerShell 1.0?

PowerShell engine events are a new feature in PowerShell 2.0.
