Hyper-V, Credential Guard, Device Guard, or why doesn’t VMware Workstation or VirtualBox work on Windows 10?

Posted by essjae on June 21, 2019

It’s frustrating if you’re seeing the the message from VMware Workstation about Device Guard or Credential Guard or the similar one from VirtualBox.

But, there are a few thing to clarify before going off on a search for those devices.¬† First, if you’ve got Hyper-V installed, that is the most likely culprit here and disabling or removing that feature should solve your issue.

Some things to consider:

If you’ve got Windows 10 Home, then you don’t have Hyper-V enabled. See: https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/hyper-v-requirements

If you have Windows 10 Home or Pro you do not have Credential Guard enabled.  It is a feature only in Enterprise, Education, and IoT Enterprise versions of Windows 10. See: https://docs.microsoft.com/en-us/windows/security/identity-protection/credential-guard/credential-guard-requirements

 

This is great info, but what do you do about getting Workstation or VirtualBox to work?

Again, the most likely culprit is Hyper-V.  Disabling or removing and a reboot should resolve this.

Disable or Remove Hyper-V

Disable Hyper-V

Open an elevated command prompt or PowerShell (right-click and select Run as Administrator)

Enter: bcdedit /set hypervisorlaunchtype off

Reboot.  (To re-enable Hyper-V, open an elevated prompt and enter:  bcdedit /set hypervisorlaunchtype auto and reboot.)

Remove Hyper-V

Go to Control Panel–>Programs and Features, select Turn Windows features on or off.

Expand Hyper-V, then expand Hyper-V Platform.

Uncheck Hyper-V Hypervisor.

Reboot.  Please note that removing Hyper-V could affect the functionality of other features of Windows 10 such as Docker.

Windows Hypervisor Platform

While this is supposed to allow 3rd party virtualization to access the hardware virtualization on the host, it doesn’t seem to work for either Workstation or VirtualBox.¬† Workstation¬† gives the same standard Credential Guard message.¬† VirtualBox is supposed to work per their changelog, but the communities have posts reporting failure and a bug report on it.

Disable Windows Hypervisor Platform

Go to Control Panel–>Programs and Features, select Turn Windows features on or off.

Uncheck Windows Hypervisor Platform

Reboot.

 

Disable Device Guard

Editing the Registry will disable this feature.  Please make sure you have a backup of your system, as editing the Registry can result in an unusable or broken Windows.

Edit the following key:  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity

Set:¬† Name = “Enabled”¬† Type =dword¬† Data =¬†0

Reboot.

Alternately, you can use the Local Group Policy Editor to manage Device Guard.

Start gpedit.msc or find Local Security Policy from the start menu.

Expand Computer Configuration\Administrative Templates\System\Device Guard and change the state to¬†disabled.¬† If you see the same settings as below, you probably don’t have Device Guard enabled.

Credential Guard

Credential Guard is controlled via Group Policy, so it’s likely that if this is the issue, you’ll be unable to do anything about it yourself.¬† You’ll need to contact your IT department to have this turned off.¬† Again, Credential Guard is only available on Enterprise, Education, and IoT Enterprise.¬† If you don’t have one of these versions, this isn’t the culprit.

 

Antivirus Utilities

There is one more culprit that could be causing the issue.  Some antivirus software blocks hardware virtualization.

Check with your antivirus vendor to confirm this isn’t an issue and if there is a way to disable it on your AV software.

 

Due to the various builds of Windows 10, you might not find these settings in exactly the same place as described or shown.

Easy (lazy) way to get your serial number for your Dell, or other OEM system?

Posted by essjae on November 15, 2016

Need your serial number? ¬†Laptop’s docked, or workstation not easily accessible?

Here’s an easy way to get your vendor serial number:

  1. Start a command prompt, click start, type “cmd”, hit enter
  2. type “wmic bios get serialnumber”

This will return your Dell, Lenovo, etc serial number.

Note: If you have a custom or home built system, you’re not likely to get an serial number, you’ll probably see something like ¬†“system serial number” or “to be filled in by o.e.m”

Don’t ask, don’t tell…Apple’s policy on Mac malware

Posted by essjae on May 19, 2011

Ars has a wonderfully insightful article with internal Apple memos regarding the Mac Defender malware.  The best part, Apple says to tell customers:

  • Do not confirm or deny that any such software has been installed
  • Do not attempt to remove or uninstall any malware software
  • Do not send escalations or contact Tier 2 for support about removing the software, or provide impact data.
  • Do not refer customers to the Apple Retail Store.¬† The ARS does not provide additional support for malware.

Even more telling: “Apple’s [IT] department mandates the use of Norton Antivirus on company machines.”

nVidia Geforce 270.61 drivers released!

nVidia, the dreamcrusher

Posted by essjae on October 28, 2010

Everytime nVidia releases a new version of the video card drivers, I keep up the hope that it will fix the “Display driver NVIDIA Windows Kernel Mode Driver, Version XXX.XX stopped responding and has successfully recovered.”

I was hoping 260.99 would be the one…after all this has only affected every driver release since at least 195.62 which was back in December 2009.¬† Unfortunately, less than 24 hours after updating my drivers, the first error popped up.¬† Since this is on my Dell laptop, I’ve got no option for swapping out the video card.

Displayport adapters aren’t perfect

Posted by essjae on February 10, 2010

 

Every once and a while I get a link failure…only way I’ve found to fix it so pull and re-plug in the adapter from the card.

Update:¬† The lastest drivers from AMD seem to have resolved this issue.¬† I haven’t lost my display port for a couple months now.
