Disabling-Hyper-V

Certain advanced Windows 10 features, such as Device Guard (in particular, Hypervisor-protected code integrity or HVCI) and Credential Guard, can prevent Hyper-V from being completely disabled. In other words, when any of these features are enabled, so is Hyper-V, even though Windows may report otherwise.

The Device Guard and Credential Guard hardware readiness tool released by Microsoft can disable the said Windows 10 features along with Hyper-V:

  1. Download the latest version of the tool from here dgreadiness-tool. The following steps assume version 3.6.
  2. Unzip.
  3. Open an elevated (i.e. Run as administrator) Command Prompt.
  4. @powershell -ExecutionPolicy RemoteSigned -Command "X:\path\to\dgreadiness_v3.6\DG_Readiness_Tool_v3.6.ps1 -Disable"
  5. Reboot.
