Powershell for removing disconnected users

Hey all,

Just wanted to share a simple script I use to remove hanging disconnected users from my farm.

Everything I've seen so far for dealing with disconnected users on vWorkspace has been directed to people using RDSH (using group policy if I remember correctly).  For those of us that don't use RDSH (I have desktops on vSphere myself) there didn't seem to be any solutions.  I have a pretty small environment still in it's testing phase so please use caution, etc, if you decide to borrow from this.

So using the new-ish PowerShell module 7.5.304.0071 I whipped up a simple script that I just run as a scheduled task.  The actual part of the script that disconnects users is at the bottom - the rest is to deal with the occasional issue of when a desktop that has a disconnected user gets suspended.  If you don't use power savings on your pool (and thus don't end up with suspended vm's) you can safely ignore that part.  I also love transcripts for PS scripts so if you don't you can remove that too!

Anyway, here is the code
