Using Remote Desktop to access Windows 10 VM causes it to lock-up

Question

I have a windows 10 host running hyper-v. It has a VM also running windows 10. If I use remote desktop services to log in to the VM, almost immediately after providing password and hitting enter, the entire VM becomes unresponsive. I might see the status circle dots spin a couple of times but then stop.

I check hyper-v manager and it looks pegged at 16% (there are two virtual processors) - not sure if it is significant.

I attempt to use Hyper-V manager to Connect to the VM, but it can't connect.

I'm not sure where to look for errors. The event viewer on the VM didn't seem to have anything useful.

I end up having to switch the VM off and on again.

Any ideas to fix / trouble-shoot would be welcome.

Thanks!

Answer 1

I posted the question to technet and thanks to some posts and my own investigations I found the following workarounds:

1. If you want to use Remote Desktop and save the password: Disabling "Use WDDM graphics display driver for Remote Desktop Connections" group policy setting appears to be a successful workaround when you have saved credentials for the connection / rdp file. See mid-way down on this page
2. If you want to use Remote Desktop but don't want to change group policy: Save an rdp file for the RDS and tick the checkbox to always ask for credentials.
3. Use the Hyper-V manager's Connect action.
