Virtualization applications do not work together with Hyper-V, Device Guard, and Credential Guard


Many third-party virtualization applications do not work together with Hyper-V. Affected applications include VMWare Workstation and Virtual Box. These applications might not start virtual machines, or they may fall back to a slower, emulated mode.

These symptoms are introduced when the Hyper-V Hypervisor is running. Some security solutions are also dependent on the hypervisor, such as the following:

  • Device Guard
  • Credential Guard

To determine whether the Hyper-V hypervisor is running, follow these steps:

  1. In the search box, type msinfo32.exe.
  2. Select System Information.
  3. In the detail window, locate the following entry:
    A hypervisor has been detected. Features required for Hyper-V will not be displayed.


This behavior occurs by design.

Many virtualization applications depend on hardware virtualization extensions that are available on most modern processors. This includes Intel VT-x and AMD-V. Only one software component can use this hardware at a time. The hardware cannot be shared between virtualization applications.


To use other virtualization software, you must disable Hyper-V Hypervisor, Device Guard, and Credential Guard. If you are using Hyper-V to run virtual machines or containers, disable Hyper-V Hypervisor in Control Panel or by using Windows PowerShell. To do this, use the following methods, as appropriate.

Method 1: Disable Hyper-V in Control Panel

To disable Hyper-V in Control Panel, follow these steps:

  1. In Control Panel, select Programs and Features.
  2. Select Turn Windows features on or off.
  3. Expand Hyper-V, expand Hyper-V Platform, and then clear the Hyper-V Hypervisor check box.

Method 2: Disable Hyper-V in PowerShell

To disable Hyper-V by using Windows PowerShell, follow these steps:

  1. Open an elevated PowerShell Command Prompt window.
  2. At the command prompt, run the following command:
    Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor 
Method 3: Disable Device Guard and Credential Guard

Disable Device Guard and Credential Guard by using registry keys or group policy. To do this, see the following TechNet topic:
