As promised I posted a quick video (OK not too quick) to walk through using the PowerShell pieces of GPO Reporting Pak to remove empty GPOs.
The previous post describes the process and this video simply provides the walk through. There are so may things that one can do with the GPO Reporting Pak and once you fully embrace PowerShell you significantly extend your reach. Let us know what other areas you would like to explore and we will do our best to add content to assist!
Enjoy!
