Enabling Remote Desktop
If you installed Hyper-V Core, run this to enable remote desktop:
cscript C:\Windows\System32\Scregedit.wsf /ar 0
To Enable Connections from Non Server 2012 Hosts (Less secure) run:
cscript C:\Windows\System32\Scregedit.wsf /cs 0
(Note - This isn't needed with So You Start Hyper V Core installations)
Enable remote Desktop through the firewall
Enable-NetFirewallRule -DisplayGroup "Remote Desktop"
