Niner since 2011
Oops! I asked my question befoere I finished the video. Although the question about WS2008R2 wasn't directly answered, the fact that they are working on an update that targets WS2008R2, it sounds like the current version may have issues on that OS.
Still looks like a great tool!
Can this script be used on Windows Server 2008 R2? I like building Dev VMs on that OS to allow more isolation/customization of the host enviroment.
