Run Hyper-V and VMware virtual machines on Windows 10

I use Windows’ Hyper-V to run virtual machines for long time. Recently I need to run a VMware virtual machine to test something. I installed VMware Player, which is free for non-commercial usage. However, the virtual machine cannot started, with an error:

VMware Player and Device/Credential Guard are not compatible. VMware Player can be run after disabling Device/Credential Guard. Please visit http://www.wmware.com/go/turnoff_CG_DG for more details.

The link will redirect you to a document with many steps.

  1. Disable the group policy setting that was used to enable Credential Guard.

    1. On the host operating system, click Start > Run, type gpedit.msc, and click Ok. The Local group Policy Editor opens.
    2. Go to Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security.
    3. Select Disabled.
  2. Go to Control Panel > Uninstall a Program > Turn Windows features on or off to turn off Hyper-V.
  3. Select Do not restart.
  4. Delete the related EFI variables by launching a command prompt on the host machine using an Administrator account and run these commands:
    mountvol X: /s
    copy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Y
    bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloader
    bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"
    bcdedit /set {bootmgr} bootsequence {0cb3b571-2f2e-4343-a879-d86a476d7215}
    bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO,DISABLE-VBS
    bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:
    mountvol X: /d
    Note: Ensure X is an unused drive, else change to another drive.
  5. Restart the host.
  6. Accept the prompt on the boot screen to disable Device Guard or Credential Guard.

Actually, this is a conflict that can be simply resolved by temporarily disabling Hyper-V hypervisor:

bcdedit /set hypervisorlaunchtype off

Restart is required. Apparently, the side effect is that Hyper-V virtual machines cannot be started after this:

And so is Docker:

To get Hyper-V back, just turn its hypervisor back on:

bcdedit /set hypervisorlaunchtype auto
