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.
