Question

VBS wont disable if virtualization is on. I want VBS OFF whilst virtualization ON.

Nova 0

Tried everything: Windows reinstall, Memory Integrity off, and Hyper-V commands, but VBS still won’t turn off and system still detects a hypervisor. Im on windows 11 home btw.

Hi,

In your case, you need to disable VBS but keep Virtualization enabled because if you're using Windows 11 in UEFI mode, as soon as you enable VT-d or SVM, it will activate VBS. You can temporarily disable it using this procedure; it worked for me.

To do this, download the DBG file and extract it to a folder > open Windows PowerShell and enter the command: cd directory of the folder (for example, cd c:\DBG\) then enter the command: DG_Readiness_Tool_v3.6.ps1 -Disable

Remember, VBS will reactivate as soon as you restart your PC.

I must remember that this has a security issue, disabling it gives you access to the virtualization system in the kernel directly for whatever you are using it for.

Hi,

Are you trying to use it with VirtualBox or VMware?

After communicating with ChatGPT, it still fails to figure out the problem and ends up with the only being 2 out comes. Virtualization Off + VBS Off or Virtualization On + VBS On (No temporary fix)

The command gave a red error which, stated in the README: "Red Errors: Basic hardware/firmware features are missing that will prevent enabling and using DG/CG" So is there something I'm doing wrong or is there an alternative fix etc...

It didn't even work temporarily. I can't paste the Powershell output but here is the ChatGPT summary of the errors:

SIPolicy.p7b does not exist

Disabling Hyper-V failed

A drive with the name 'T' does not exist

Unable to find registry key/value

Output message at the end: Please reboot the machine, for settings to be applied.

Im trying on my desktop no VM

I have a program thats trying to mess around with kernel drivers and it loads a driver and asks to restart my device (I tried restarting on my own but it doesnt load the kernel driver when I do that so I need the app to restart my device, but only on my device particularly it restarts for a few seconds then goes to a black screen forever (with my devices being on))

My friend tried the same program and it worked (restarted his pc no black screen) because he was able to disable VBS while keeping virtualization enabled (he doesnt have an acer nitro v15 motherboard).

Hi,

If it's not for virtualization software, would it be for games, specifically online games like COD, BF6, or some game with DRM?

Hi,

In the case of VBS, the anti-cheat should work. What error is occurring in RE6?

Thanks

What do you mean? On my friends PC the anti cheat Battle Eye (Rainbow six siege's anticheat) does not affect his VBS.

Also theres no error in RS6 its just that I need VBS disabled otherwise the kernel program just gives a black screen instead of restarting my device

Hii,

Try the command:

bcdedit /set hypervisorlaunchtype off

Set-ExecutionPolicy Unrestricted

powershell -ExecutionPolicy RemoteSigned -Command "c:\users\micha\downloads\dgreadiness_v3.6\dgreadiness_v3.6.ps1 -Disable -AutoReboot"

it doesnt work in cmd prompt either
Ivan B 111.7K Reputation points Independent Advisor

Hi.

Run this command in CMD instead of PowerShell: powershell -ExecutionPolicy RemoteSigned -Command "c:\users\micha\downloads\dgreadiness_v3.6\dgreadiness_v3.6.ps1 -Disable -AutoReboot"

Check if the location is correct.

Now you're trying to fix what software is having problems with R6, that's a bit strange.

Hi.

Do you have Riot's Vanguard?

Open the command prompt (admin) and run the command: reg add "HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard" /v "EnableVirtualizationBasedSecurity" /t REG_DWORD /d 0 /f

Restart your PC.

I can only inform you that game modification software can cause account bans; I recommend not using it.

I have already ran that command and many like it hundreds of times and it still detects a hypervisor in systeminfo and VBS is still running. I understand the risk that I could be banned, but I can inform you its not for a cheat.

Hi,

The only thing I can imagine is that third-party antivirus or anti-cheat software is active, like Riot's, which doesn't allow disabling.

You need to have core isolation and stack protection disabled - is kernel protection disabled?

If that doesn't work, unfortunately, a clean reinstall using the USB method is necessary.

Even if it's not cheating, there's a security risk, not only with R6 but also with your Windows. It's trying to give the kernel app access to the Vt-d database; I must inform you that this is not recommended.

Thanks

This is my current device security, I also have everything else inside virus and threat protection turned off, and I don't have riot or any other anti cheat. I had this exact same problem about 3 days ago so I done a clean reinstall with USB and it didn't work so I made the question.

Hi,

That's very strange. Do you have any third-party antivirus software?

And

I'm testing with Windows 10, but I don't know why VBS isn't disabled.

Thanks

Hi,

This is very strange; reinstalling Windows 11 and running the commands should work.

Do the following: access the Start menu > Settings > System > About > System Protection > Create a new system and enter the name.

You will then disable Secure Boot.

After that, download the script: https://github.com/Zelros02/DisableVBS-DeviceGuard/releases/tag/tag1

Run it as administrator. It will restart and open a prompt asking for confirmation; press F3.

AI answer

On Windows 11, VBS (virtualization-based security) and Memory integrity (HVCI) are implemented on top of the same Hyper-V hypervisor that is also used by other virtualization features. If a hypervisor is detected as running, at least one Hyper‑V–based feature is still enabled.

Key points from the provided information:

Memory integrity/HVCI is a VBS feature
- Memory integrity (also called HVCI) is a VBS feature that uses the Windows hypervisor to create an isolated environment and enforce kernel-mode code integrity.
- It is enabled by default on most new Windows 11 devices and on Secured-core PCs.
- Even if Memory integrity is turned off in the Windows Security UI, other VBS or Hyper‑V–based components can still cause the hypervisor to start.
Hyper‑V and VBS are tightly coupled
- Some Windows security technologies depend on Hyper‑V, including:
  1. Memory Integrity (HVCI)
  2. Credential Guard
- To use third‑party virtualization apps that require no hypervisor, Hyper‑V must be disabled, and these dependent features must also be disabled.
- If the hypervisor is still detected after turning off Memory integrity, another Hyper‑V–based feature (for example, Credential Guard or Virtual Machine Platform) is likely still active.
How to verify that the hypervisor is running
- Run msinfo32.exe.
- In System Information, look for the line: A hypervisor has been detected. Features required for Hyper-V will not be displayed.
If this line is present, the Hyper‑V hypervisor is running because at least one Hyper‑V/VBS feature is enabled.
How to disable Hyper‑V (and thus VBS) when needed To stop the hypervisor (and therefore VBS) from starting, all Hyper‑V–based features must be disabled. The context provides these supported methods for disabling Hyper‑V itself:
- Control Panel → Windows Features
  1. Open Control Panel → Programs and Features.
  2. Select Turn Windows features on or off.
  3. Expand Hyper‑V → Hyper‑V Platform.
  4. Clear the Hyper‑V Hypervisor checkbox.
- PowerShell (elevated)
```
     Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor
```
- DISM (elevated Command Prompt)
```
     DISM /Online /Disable-Feature /FeatureName:Microsoft-Hyper-V-Hypervisor
```
Additionally, any dependent features such as Memory integrity and Credential Guard must be disabled via Intune, Group Policy, or registry as documented in:
- Configure Credential Guard
- Enable virtualization-based protection of code integrity
VBS off while “virtualization on”
- The documentation indicates that VBS and Memory integrity explicitly rely on the Windows hypervisor. If the hypervisor is running for VBS/HVCI, that is the same virtualization layer used by Hyper‑V.
- To have VBS fully off, the hypervisor must not start for security features. That means all VBS/HVCI/Credential Guard–related components must be disabled. If any of them remain enforced by policy or OEM configuration, the hypervisor will continue to start and VBS will remain active.

In summary: on Windows 11, VBS cannot be active without the hypervisor, and if the hypervisor is still detected after turning off Memory integrity, another Hyper‑V–based security feature or policy is still enabling it. Fully disabling VBS requires disabling Hyper‑V and all dependent security features; otherwise, the system will continue to report that a hypervisor is present.
