Windows 10 Hyper-V keep crashing

Question

I have a Windows 10 build 1511 host, running a Hyper-V guest of Windows 10 build 1511 as well.

The guest runs fine on Standard Mode. However, as soon as I switch to Enhanced Session mode, the VMConnect.exe process crashes. It happens with RDP too.

Anybody knows a workaround ?

Here are the EventViewer errors:

Error Source: Application Error

Answer 1

WOW, is this really 2 years old issue unsolved by Microsoft? They are really good on bug fixing :( I have same issue after a fresh install on win 11.

Faulting application name: VmConnect.exe, version: 10.0.22621.1, time stamp: 0xaad5fb25
Faulting module name: LMFX1N4Z.DLL, version: 0.0.1.0, time stamp: 0x61b8cf09
Exception code: 0xc0000005
Fault offset: 0x0000000000038ac3
Faulting process ID: 0x0x11AC
Faulting application start time: 0x0x1D93EC841376850
Faulting application path: C:\Windows\system32\VmConnect.exe
Faulting module path: C:\Windows\system32\spool\DRIVERS\x64\3\LMFX1N4Z.DLL
Faulting package full name: 
Faulting package-relative application ID: 

So the error is related to the LMFX1N4Z.DLL dll, which is provided by Lexmark driver, so by turn off printer share with the VM it will stop crashing.
