Unknown Devices when installing Hyper-V on Windows 10

The following unknown device IDs will pop-up when you run the script or when you open Device Manager:

ROOT\VMBUS\0000
ROOT\VID\0000
ROOT\VPCIVSP\0000
ROOT\STORVSP\0000
ROOT\SYNTH3DVSP\0000

If you want to find all Unknown Devices, open PowerShell as an Administrator and run:

Get-WmiObject Win32_PNPEntity | Where-Object{$_.ConfigManagerErrorCode -ne 0} | Select DeviceID

On my work notebook, all drivers were correctly populated so it had to be something with my test laptop. It’s a fresh Windows 10 machine deployed by a Task Sequence – enabled with Device Guard and Credential Guard.

Solution:
During the installation I’ve installed the Microsoft-Hyper-V-Hypervisor feature on Windows 10. You also need to install the Microsoft-Hyper-V-Services if you want to have those drivers installed as well.

Screen display flashes or blinks if Device Guard or Credential Guard with Hyper-V has been enabled

When you enable Device Guard or Credential Guard with Hyper-V on your system, your screen will blink every X seconds. This is a really annoying bug and has been fixed by Intel.

Solution:

Upgrade your Intel(R) HD Graphics driver to version 20.19.15.4352.
