The Issue:
I am trying to disable Hyper-V, but Windows refuses to unload its own Hypervisor.
In `msinfo32`, it persistently shows:
A hypervisor has been detected. Features required for Hyper-V will not be displayed.

My Hardware:
* **CPU:** i7-12700K
* **Motherboard:** MSI MPG Z690 EDGE WIFI DDR4
* **OS:** Windows 11 25H2
* **BIOS Settings:**
* VT-x (Virtualization): **Enabled**
* VT-d (IOMMU): **Disabled**
* Kernel DMA Protection: **Disabled**

What I have already tried:
  • Group Policy & Windows Features
    GPEDIT: `Local Computer Policy > System > Device Guard` -> **Turn On Virtualization Based Security** set to **Disabled**.
    Disabled Features: Virtual Machine Platform, Windows Hypervisor Platform, Hyper-V, and WSL.
  • BCD / Boot Configuration (Ran as Admin)
    bcdedit /set vsmlaunchtype Off
    bcdedit /set hypervisorlaunchtype off
    bcdedit /deletevalue {current} vsmlaunchtype
  • Deep Clean Tools: (I wanted to disable VBS, and now Virtualization-based security is not enabled, just as I planned)
    - Ran `DG_Readiness_Tool_v3.6.ps1 -Disable -AutoReboot`.
    - Confirmed the UEFI black screen prompt to disable Device Guard/Credential Guard upon reboot.
  • Registry
    `HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard` -> Set `EnableVirtualizationBasedSecurity` to **0**.
  • DISM Feature Removal (Ran as Admin)
    Code:
    dism /online /disable-feature /featurename:Microsoft-Hyper-V-All
    dism /online /disable-feature /featurename:VirtualMachinePlatform
    dism /online /disable-feature /featurename:HypervisorPlatform
  • Software Context (VMware)
    - I have VMware Workstation installed, but I have **disabled all VMware services** (set to Manual/Stopped) to ensure they aren't triggering the hypervisor.
Current Status:
Despite all of the above, `msinfo32` still says a hypervisor is detected.

What about in Windows features? Are the ones on screenshot below still checked?
You would think that they would be off with the DISM commands you used but double check anyway.
But I see you did not use the powershell command:

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

Again, you would think that was covered with what you did, but it will not hurt to run that one and it will ask for a restart.

May I ask why you want to disable the Windows Hypervisor?

Please refresh the page as I have posted additional content.
I also wanted to add that Hypervisor & Broadcom VMWare can run together as the screenshot below shows.
I never disable the hypervisor as I use Sandbox.
I run 2 Windows VMs & 1 Linux VM without any performance penalty.

I need VMware Workstation to run using native VT‑x, and I also want to improve overall system performance.
Code:
Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All
I believe I already ran that command earlier, but I’ll run this specific PowerShell command again now just to be absolutely sure.

Here is the latest update. I have completely stripped the Secure Boot keys and checked for any lingering drivers.

BIOS Status:
Secure Boot Mode: Custom
Action Taken: Delete All Secure Boot Keys.

Driver Filter Check (fltmc):
I checked for rogue drivers (like VMware) but the list looks clean.

Current Situation:
Despite deleting winsipolicy.p7b from the EFI partition, deleting all Secure Boot keys in BIOS, and having no active virtualization drivers... msinfo32 still shows "A hypervisor has been detected".

Turn off hardware virtualisation from the bios.
Do you mean disabling VT-x (Intel Virtualization Technology)?

If I do that, it will prevent VMware Workstation from running (since VMware requires VT-x to function).

My specific goal is to have Hardware Virtualization (VT-x) ENABLED, but the Windows Hypervisor/VBS software layer DISABLED, so that VMware can use the hardware directly.

Turn off hardware virtualisation from the bios.
I just disabled VT-x in BIOS to test, and msinfo32 showed:

Code:
Hyper-V - VM Monitor Mode Extensions    Yes
Hyper-V - Second Level Address Translation Extensions    Yes
Hyper-V - Virtualization Enabled in Firmware    No
Hyper-V - Data Execution Protection    Yes

This confirms the Windows Hypervisor was gone, but "Virtualization Enabled in Firmware" was No, which breaks VMware.

However, the moment I re-enabled VT-x in BIOS and restarted, msinfo32 immediately reverted to:
Code:
A hypervisor has been detected. Features required for Hyper-V will not be displayed.

This confirms that enabling Hardware Virtualization (VT-x) is instantly triggering the Windows Hypervisor to load, ignoring my BCD "off" settings.

Is there any way to see exactly what hypervisor or feature is being detected? I've checked fltmc for drivers and Event Viewer for Code Integrity policies, and both are clean. What is the next step to trace this?

Yes, Virtualization (VT-x) is definitely Enabled in my BIOS.

That is actually the problem. When I enable it, Windows sees it and immediately loads its own hidden Hypervisor, which locks out VMware from using the hardware directly.

I am trying to achieve this specific state in msinfo32:

Code:
Hyper-V - VM Monitor Mode Extensions    Yes
Hyper-V - Second Level Address Translation Extensions    Yes
Hyper-V - Virtualization Enabled in Firmware    Yes   <-- I need this YES
Hyper-V - Data Execution Protection    Yes

Currently, I get "A hypervisor has been detected," which means the Windows software layer is active and blocking me from that raw hardware access.1768932411849.webp

As a test... go into the BIOS and DISABLE Virtualization, then save and boot into Windows and see if that affected the hypervisor problem.

If it doesn't help, then go back to the BIOS and re-enable it.


And here's ten points, just for filling out "most" of your computer specs. :-)

    Still assembled, still runs. Haven't turned it on for 15 years?
@Ghot
Thanks! I actually tried exactly that earlier in the troubleshooting process.

When I DISABLE Virtualization (VT-x) in the BIOS, the "A hypervisor has been detected" message disappears, and msinfo32 shows this:

Code:
Hyper-V - VM Monitor Mode Extensions    Yes
Hyper-V - Second Level Address Translation Extensions    Yes
Hyper-V - Virtualization Enabled in Firmware    No
Hyper-V - Data Execution Protection    Yes

However, as soon as I go back to BIOS and RE-ENABLE it (which I need for VMware), the message "A hypervisor has been detected" comes back immediately.

This confirms that the Windows Hypervisor is launching specifically because it detects the hardware capability, effectively hijacking it before VMware can get to it.

Okay, I think I've figured out what's happening. Windows seems to be "healing" itself and forcing these settings back on after every reboot.

I was following Step 6 from this Broadcom guide (https://community.broadcom.com/vmwa...ion/how-to-disable-hyper-v-in-windows-11-24h2) using the official Device Guard and Credential Guard hardware readiness tool.

Here is the pattern I found:

1. I ran the readiness tool script and rebooted. VBS turned "Not Enabled", but the Hypervisor message was still there.
2. I ran the script again immediately after. This time it actually worked! The "Hypervisor detected" message disappeared and everything looked correct.
Like this
Code:
Hyper-V - VM Monitor Mode Extensions    Yes
Hyper-V - Second Level Address Translation Extensions    Yes
Hyper-V - Virtualization Enabled in Firmware    Yes
Hyper-V - Data Execution Protection    Yes
3. But then I did a normal restart (without using the tool), and it completely reverted. Both VBS and the Hypervisor are active again.

This is what msinfo32 shows now after that normal restart:
Code:
Virtualization-based security    Running
Virtualization-based security Required Security Properties   
Virtualization-based security Available Security Properties    Base Virtualization Support, Secure Boot, UEFI Code Readonly, SMM Security Mitigations 1.0, Mode Based Execution Control, APIC Virtualization
Virtualization-based security Services Configured   
Virtualization-based security Services Running   
A hypervisor has been detected. Features required for Hyper-V will not be displayed.

Btw, VT-x was enabled in BIOS throughout all these steps.

Nothing more frustrating than trying to hack into your own computer to regain control of it. Have you tried booting into safe mode and removing the hyper-v services?

None. Manully configured so nobody except me can change any critical system files. (Don't ask how, it's probably against some rule somewhere)
That msinfo32 line isn't very specific so not sure what to make of it in the end. What hypervisor is detected if all features are disabled...
More important is a stable system and that VMs run fine without hiccups.
After trying all those steps, does VMware Workstation actually work normally or do you get slowdowns and mentions of Hyper-V mode?

Open traditional Control Panel, switch from group to large icons top right, open Add/Remove Programs and then click to open Turn Windows Features On or Off. Scroll down, there is not only Hyper-V, but also Windows Supervisor Platform and Virtual Machine Platform. Make sure you also disable these two:
