Why is Hyper-V crashing on enhanced session mode?


I'm running a Windows 10 Enterprise build 1607 guest on my Windows 10 Pro build 1607 host machine. I'm not doing it for any useful purpose; just so I can mess around with some Windows settings without doing harm to my host machine.

However, if I use Enhanced Session Mode, VMConnect.exe will inevitably crash. This generally happens when browsing Chrome, or pretty much doing anything else on the VM. When it crashes, the VM still runs and I can connect to it. However, it'll likely crash if I continue to use it on Enhanced Session Mode. Regular session mode works fine, and I would use it to avoid this crashing, but I can never get the screen resolution right.

Any ideas as to identify the culprit? I'll attach an EventViewer log, but I don't know how far that'll go. Probably better, I attached a dump file as well, here.

The audio codec vorbis.acm causes the crash:

Faulting module name: vorbis.acm, version:, time stamp: 0x50a51541

update or remove the software that uses/install vorbis.acm.
