I've got a Generation 2 VM running Windows 8.1. It has secure boot disabled and lists the VMs version as 5.0. Hyper-V itself is version 6.3.9600. This morning, about 4 hours ago, it started a Windows Update and rebooted. While I was connected to it I could see the message along the lines of "Windows is making configuration changes, do not turn off your computer".
I left it running and my connection to it timed out. Now I can't connect to it anymore. When I try to connect, it refuses with the message: "Video Remoting was Disconnected"
The "Heartbeat" says "OK (Applications Healthy)" so I'm guessing I wont be able to connect until it's finished the update but I'm starting to wonder if it's just hanging or crashed.
Is there a way of telling if it's really making any progress with the update? Should I risk turning it off and then on again?
Update: I have one error in my Application Event Viewer, complaining that mshta.exe was suffering from an "Application Hang" error:
The program mshta.exe version 11.0.9600.17416 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Action Center control panel.

Not sure if it's a coincidence or not but it occurred around the time I noticed my VM hanging.
