cmd - VMware Workstation and Device/Credential Guard are not compatible

Question

I have been running VMware for the last year no problems, today I opened it up to start one of my VM and get an error message, see screen shot.

I did follow the link and went through the steps, on step 4 I need to mount a volume using "mountvol". when I try to mount a volume using mountvol X: \?Volume{5593b5bd-0000-0000-0000-c0f373000000} it keeps saying The directory is not empty. I even created a partition with 2GB and still the same message.

My Questions:

How can I mount the volume that is not empty even though it is?

Why did this Device/Credential Guard auto enable itself and how can I get rid of it or disable it.

Answer 1

There is a much better way to handle this issue. Rather than removing Hyper-V altogether, you just make alternate boot to temporarily disable it when you need to use VMWare. As shown here...

http://www.hanselman.com/blog/SwitchEasilyBetweenVirtualBoxAndHyperVWithABCDEditBootEntryInWindows81.aspx

C:>bcdedit /copy {current} /d "No Hyper-V" 
The entry was successfully copied to {ff-23-113-824e-5c5144ea}. 

C:>bcdedit /set {ff-23-113-824e-5c5144ea} hypervisorlaunchtype off 
The operation completed successfully.

note: The ID generated from the first command is what you use in the second one. Don't just run it verbatim.

When you restart, you'll then just see a menu with two options...

• Windows 10
• No Hyper-V

So using VMWare is then just a matter of rebooting and choosing the No Hyper-V option.

If you want to remove a boot entry again. You can use the /delete option for bcdedit.

First, get a list of the current boot entries...

C:>bcdedit /v

This lists all of the entries with their ID's. Copy the relevant ID, and then remove it like so...

C:>bcdedit /delete {ff-23-113-824e-5c5144ea}

As mentioned in the comments, you need to do this from an elevated command prompt, not powershell. In powershell the command will error.

update: It is possible to run these commands in powershell, if the curly braces are escaped with backtick (`). Like so...

C:WINDOWSsystem32> bcdedit /copy `{current`} /d "No Hyper-V"
