I have enabled the Enhanced session on the Hyper-V manager and the Guest services in the integration services.


The below screen shows up once i reboot the server but i forgot to press show option to enable PNP.

Is there a way to open the below screen again please.

Hyper-V Enhanced Session Mode 'Intercept' Stopped Working

The RDP config file for a VM is only created when enhanced mode settings are saved. If user switches to enhanced mode without saving the settings, no RDP configuration file will be created.

To save configuration, first switch to enhanced mode:





Click Show Options:





Select Save my settings and click Connect:

In normal mode, resolution can be changed exactly as on physical machines, right click on desktop and select Display Settings.

When switching to enhanced mode on a VM with no configuration saved, use the slider in VM Connect window to set resolution:

 

Hyper-V Enhanced Session Mode 'Intercept' Stopped Working

As I said in my previous post, enhanced mode ONLY works on virtual machines with Windows 8.1 or later. See the note in beginning of this tutorial: Turn On or Off Hyper-V Enhanced Session Mode in Windows 10 | Tutorials

 

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?
