Windows 10: Hyper-V Enhanced Session Mode 'Intercept' Stopped Working

WIN 10 build 1809. Very strange problem. Hyper-V was working fine with enhanced sessions and then went south. Checked Hyper-v settings and both Server -- > Enhanced Session Mode Policy and User --> Enhanced Session Mode are checked. With new virtual machines there is no opportunity to set resolution, etc.
Turning off and on enhanced settings -- no joy. There are no files in the vmconnect directory that correspond to my present VMs, only one old one vmconnect.rdp.xxxxxxxxxx.
I need to change the video size for my existing vm's, but cannot. For a Linux VM I managed to change the video size by modifying the GRUB_CMDLINE_LINUX_DEFAULT in Linux.
Another important piece: I also use viboot under Macrium to create VMs from backups and it works perfectly:
the enhanced box pops up on every start to change parameters. Macrium uses Hyper as a back end.
Why isn't hyper-v creating vmconnect.rdp files for new VMs? What can I do to further troubleshoot this issue?

Hyper-V in Windows 10 1709 FCU, enhanced session not working?


I have a fresh install of Windows 10 1709 Education N, and using the same image I made a Gen2 VM in Hyper-V.
I thought something was off and then I noticed that enhanced mode wasn't on at all, and it is greyed out in the menu. It is enabled in Hyper-V settings. I only found results about enhanced session crashing (in FCU), but mine's not on at all.
Anyone else experiencing the same issue, or is it perhaps working for you guys?

https://docs.microsoft.com/en-us/win...with-vmconnect I have went through this guide, and I am not presented with any extra connect options with vmconnect. It just goes straight to the VM.

Here are my Hyper-V settings: https://i.imgur.com/dheqZsB.png (the issue was there before adding the remotefx adapter).

In previous versions of Windows 10 (Edu N 1703), with the same exact steps that I've done here (same image for host + guest), enhanced mode worked right out of the box, no extra fiddling.

RDP is turned on?

Great - great feedback - this helps us all.

Suggest you report back on other forum as well.

Incidentally, sometimes you have to shutdown vm and reboot for enhanced mode to kick in - maybe that was problem first time?
