How to disable virtualization?

Question

How to disable virtualization? I have tried unchecking Virtual Machine and Hyper V in the control Panel. I have turned off the feature in Core Isolation. A Microsoft agent tried a couple of commands, to no avail. I have spoken to 15 different agents between the Surface and Windows team and not one person knows how else to turn it off. The reason we can tell that its on is if you look in CPU its still enabled. I need it turned off for a client’s secure remote access. I cannot wait up to 72 hours for a tier2 person to contact me as i need it turned off now; otherwise i can lose the client.

Hi Tracey,

Hope you're doing well.

To disable virtualization, you can try the following methods:

1. Restart your computer and enter the BIOS/UEFI settings. Then look for virtualization technology in system settings or advanced settings. Set the virtualization technology option to disable or off. Save the settings and restart your computer.
2. Open Command Prompt (run as administrator) and run the following command to disable Hyper-V:

bcdedit /set hypervisorlaunchtype off

Restart your computer.

Best Regards

A couple of Microsoft agents have already tried this and it didn't work. It is still turned on. The Surface Go does not have the virtualization option in UEFI. Any better ideas?

Hi Tracey,

Sorry for the late response.

1. Sometimes virtualization features are controlled via Group Policy settings. Open the Group Policy Editor by typing "gpedit.msc" in the Windows search bar and navigate to "Computer Configuration" > "Administrative Templates" > "System" > "Device Guard" > "Turn on Virtualization Based Security." Set this policy to "Disabled."
2. Virtualization features can also be controlled via registry settings. However, modifying the registry should be done with caution as it can impact system stability if done incorrectly. If you're comfortable with registry editing, you can navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard and look for keys related to virtualization. Set any relevant keys to 0 or delete them (after backing up the registry).

Best Regards

Hi Tracey,

Thanks for the update.

If none of the above steps resolve the issue, it's possible that there may be a specific configuration or issue related to your hardware. Contacting your computer's manufacturer support team for assistance may be necessary.
