If you have a spare Windows 7 key, I'd suggest a Win7 VM with Teamviewer Host. The host version of Teamviewer only allows incoming connections, and I set it up so it only allows requests from my Teamviewer account and blacklists all others. The kicker is that after I did all the Windows updates, the "Upgrade to Win 10 for free" dialog came up, so now I have a third home computer that will be upgrading at no extra cost!
The Unraid VM installation guide on the wiki was easy to follow, and worked fantastically for me (good job guys!)
Works great on my old Q6600 with Cores #2 and #3 allocated (#0 and #1 are not allocated to the VM), 50GB image size (windows updates required ~30GB minimum), and 4GB RAM(of 8GB installed).
