Hello everyone,

I've big issue with my hyper-v on windows server 2022.

I can't connect anymore with the console en Hyper-v manager.

All my VM are working as expected but it's not possible to use the VMCompute anymore to deploy new VM.

I've tried a lot of trick without any positive result. I've also tried with WAC with the same result.

I've seen this error in event logs but i can't start and stop Vmcompute services as expected, too.

Fault services: vmcompute.exe

Exception: 0xc0000194

Defective module: vmcompute.exe.

Already tried to disable Firewall and AV and so on.

Did you have an idea of what could happen?

Many thanks.

    Hi Christopher Migeot,

    The error code 0xc0000194 typically points to a failed initialization or missing component within the VM compute stack.

    Here are a few steps I recommend trying:

    First, open Services.msc, locate Hyper-V Host Compute Service, and ensure the startup type is set to Automatic. Try starting it manually.

    If it fails, open an elevated PowerShell window and run:

    sfc /scannow  
DISM /Online /Cleanup-Image /RestoreHealth

    These commands will check for and repair corrupted system files.

    Verify that all Hyper-V-related Windows features are enabled by running:

    dism /online /enable-feature /featurename:Microsoft-Hyper-V-All /all

    Check the folder C:\ProgramData\Microsoft\Windows\Hyper-V for permission issues — ensure SYSTEM and Administrators have full control.

    If the service still won’t start, you may need to re-register VMCompute using:

    net stop vmms  
net stop vmcompute  
del "%ProgramData%\Microsoft\Windows\Hyper-V" /F /S /Q  
net start vmms

    If everything looks correct and the issue persists, consider performing a repair installation of Windows Server 2022 while keeping roles and data intact.
