Virtualization applications don't work together with Hyper-V, Device Guard, and Credential Guard
Many third-party virtualization applications don't work together with Hyper-V. Affected applications include VMware Workstation and VirtualBox. 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:
- Device Guard
- Credential Guard
Original product version: Windows 10 - all editions

Determine whether the Hyper-V hypervisor is running
To determine whether the Hyper-V hypervisor is running, follow these steps:
In the search box, type msinfo32.exe.
Select System Information.
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. It 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 want to disable Hyper-V Hypervisor, follow the steps in next two sections.
