I'm looking to fully disable Hyper-V from my computer.

I need to run TwinCAT 3, which requires VT-X enabled for real-time but cannot run with Hyper-V running in any way, shape, or form.

I've disabled it every way I know how, including:

  1. Unchecking the boxes when you go to the "Turn on and off Windows Features" menu
  2. Running in powershell Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor
  3. Running in powershell bcdedit /set hypervisorlaunchtype off
  4. Turning off VT-D in the BIOS but leaving VT-X on

Still, when I look at msinfo32.exe, I see that a hypervisor has been detected at the bottom.

If you have run into this issue at all, I would greatly appreciate the insight.

    Other things use hardware virtualization in Win10/11 than just Hyper-V:

    WSL2, some antivirus apps, device guard, credential guard, etc.
