Unable to disable Hyper-V/Hypervisor in Windows 11 Build 24H2

Question

Hi,

we have a lot of new Windows 11 PCs and Laptops. We are using VMware Workstation Pro 17. Until Windows 11 Build 23H2, all is working. After updating to Windows 11 Build 24H2 we get in systeminfo that the hypervisor is detected. No VM in VMware is working any more with VT-x. VT-x is blocked as long as the hypervisor is detected. We are not able to disable or remove completely the hypervisor/hyper-v.

Here are the steps we made:

via windows settings

Windows Security => Core isolation => Memory integrity => disabled

via PowerShell as Admin

Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor

Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

DISM /Online /Disable-Feature /FeatureName:Microsoft-Hyper-V-All /NoRestart

cmd as Admin

bcdedit /set hypervisorlaunchtype off

dism.exe /Online /Disable-Feature:Microsoft-Hyper-V-All

dism.exe /Online /Disable-Feature:VirtualMachinePlatform

dism.exe /Online /Disable-Feature:WindowsHypervisorPlatform

sc config vmms start= disabled

sc config vmcompute start= disabled

sc config hvservice start= disabled

sc config hvhost start= disabled

sc config vmgid start= disabled

sc delete vmcompute

sc delete hvservice

sc delete hvhost

sc delete vmgid

via regedit:

delete

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Hyper-V

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\vmcompute

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hv

modify

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hvHost => Start = 4

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hvService => Start = 4

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Hvsi => Disable = 1

device manager:

deleted

• Microsoft Hyper-V virtualization infrastructure driver
• Microsoft Hypervisor Service

group policies:

• Computerkonfiguration => Administrative Vorlagen => System => Device Guard => Virtualisierte Sicherheit aktivieren => deactivated
• Computerkonfiguration => Administrative Vorlagen => System => Device Guard => App Control for Business bereitstellen => deactivated

tool:

DG_Readiness_Tool_v3.6.ps1 -Disable

Nothing helps. This is really frustrating.

The only thing I can do to prevent the hypervisor from starting is to deactivate VT in BIOS. But I want to use it so that can't be the solution.

I really need a solution for Windows 11 Build 24H2.

Answer 1

Hi. Phase 1 and 2 are the same what I did at very first.

Phase 1

Disable memory intergy and remove the 4 features.

Phase 2

bcdedit /set hypervisorlaunchtype off

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\DeviceGuard ->"EnableVirtualizationBasedSecurity" -> "0"

group policy -> Computer Configuration -> Administrative Templates -> System -> Device Guard -> "Disabled"

It's not working.

Phase 3

Is also not working.

I have not this SOPolicy.p7b file. I also do not know, where to find the logfile "Disbaling Hyper-V failed check the log file". If I had this logfile, maybe I could find a solution.

Answer 2

Hi,

Please first make sure the computer meets the Hyper-V system requirements.

Windows 11 Hyper-V System Requirements | Microsoft Learn

If the computer meets the requirements, perform a clean boot and try disabling Hyper-V again.

If the issue persists, since you see this issue only after upgrading to 24H2, you can go back to the 23H2 version temporarily and send feedback to Microsoft.

Answer 3

Hi,

Requirements fulfilled:

• Intel Core i5-13600 (VT is active in BIOS, and worked in Win 11 23H2)
• 64GB DDR5 RAM
• 2TB M.2-SSD

Clean Boot

I did it, but the result is the same. A hypervisor is detected. Nothing is installed, no service is running, no driver is installed, VMware and VBox is removed. Nothing helped in Version 24H2. I am sure, if I go back to 23H2 all will be fine.

Any other ideas, what do to, to solve this problem?

Answer 4

I am experiencing the same issue and I have tried a number (not all) of these fixed you posted. I just did a clean install of build 24H2 too. When I try to install VMware or try to run a memory benchmark in AIDA64 Extreme, I got the hypervisor error too. Everything worked perfectly fine in 23H2.

This is frustrating.

Answer 5

I followed Phase 1 and 2 at this link and was able to get it disabled and I no longer get the hypervisor error message while trying to install VMware and also when running AIDA64 Extreme memory benchmark. This might solve your issue too.
