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