Deleting Workflows in SCOM 2012 with PowerShell

This is a continuation of a Data Center Automation series of posts that I have been working on with Anders Bengtsson. Here are the first four posts in this series:

Creating Management Packs in SCOM 2012 with PowerShell
Creating Performance Collection Rules in SCOM 2012 with PowerShell
Creating Event Based Alerting Rules in SCOM 2012 with PowerShell

This script is also included as an activity in the Operations Manager Admin Integration Pack.

  Hey Marius, I just did a quick test on this. I deleted a rule using the script that had opens alerts associated with it. The alerts went away and I don't find any trace of them in the database. Can you give me some more details on exactly where you're seeing this? Is it just in the MP when you export it? If that is the case then is it just an annoyance or is it actually causing a problem? I know, lots of questions but I just want to make sure I completely understand the question. Thanks, Russ
