Problem:

I’ve Windows 10 Pro system, and use Hyper-V on that system. Due to the needs of device redirection doesn’t works well with Hyper-V, I’ve installed VMWare Workstation 14.

I have to disable Hyper-V to make VMWare Workstation work, at beginning. It worked until Feature update to Windows 10, version 1803 that triggered the problem with VMWare Workstation again.

  1. After Windows update completed (after reboot), I tried to start a VM in VMWare. I get the error dialog complaining about Device/Credential Guard. Please visit http://www.vmware.com/go/turnoff_CG_DG for more details.

  1. Following the instruction in this link: https://kb.vmware.com/s/article/2146361, and after the reboot, I get another complaint about incompatibility with Hyper-V.

  1. After reset the Hyper-V selection in Windows Feature or confirm that HyperV is not already removed, and reboot, the first error came back.

It gets in a loop of error complaining about Device Guard and complaining about Hyper-V for VMWare.

Solution:

Ok, thanks to the answer from communities of VMWare: https://communities.vmware.com/thread/588526

The issue is now gone, by applying the following change:

  1. Disable credential guard by using readiness tool from Microsoft: https://www.microsoft.com/en-us/download/details.aspx?id=53337, with this command: DG_Readiness_Tool_v3.2.ps1 -disable
  2. Disable Hyper-V by using PowerShell command: Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V
  3. Reboot and accept to boot without CG/DG.

Although I don’t like that VMWare cannot work together with device guard from system, I get my VM working for the moment.
