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.
- 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.
- 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.
- 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.
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:
- 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
- Disable Hyper-V by using PowerShell command: Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V
- 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.
