It looks like Hyper-V is already running

🧩 Understanding the Problem

The software checks the following conditions:

  • The hypervisor present bit is set (CPUID leaf 1, ECX bit 31)

  • The hypervisor signature is Microsoft Hv

  • Hyper-V root partition privileges are available (CPUID leaf 0x40000003, EAX bit 0)

When all three are true, it assumes Hyper-V is active — and blocks execution.

✅ Solutions (in order of recommendation)

🧨 Final Solution: HyperV Disabler Batch File

💾 Download the Disabler (press here)

This batch file provides a full Hyper-V shutdown, even when Windows still shows it as “off.”

What it does:

  • Renames the core Hyper-V executables (hvix64.exe and hvax64.exe) → to hvix64_old.exe and hvax64_old.exe

  • Ensures any remaining active Hyper-V layer is fully disabled

  • Uses RunAsTI (runs as TrustedInstaller/System)

  • Handles ownership elevation, HKCU load, and explorer support

⚠️ Important: Run the batch file as Administrator. This method has a 100% success rate when executed properly.

🧰 Solution 1: Disable Hyper-V Completely

Method A — Windows Features

  1. Open Turn Windows features on or off

  2. Uncheck all of the following:

    • Hyper-V

    • Virtual Machine Platform

    • Windows Hypervisor Platform

    • Windows Sandbox (if present)

    • WSL 2 (Windows Subsystem for Linux 2)

  3. Restart your computer.

Method B — Command Prompt (Admin)

Copy

bcdedit /set hypervisorlaunchtype off
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V

Then restart your PC.

Method C — PowerShell (Admin)

Copy

Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All
bcdedit /set hypervisorlaunchtype off

Restart required.

🕵️ Solution 2: Check for Hidden Hyper-V Services

Even if Hyper-V appears disabled, background components can keep it active.

1. Disable Windows Defender Application Guard

Copy

Disable-WindowsOptionalFeature -Online -FeatureName Windows-Defender-ApplicationGuard

2. Disable Core Isolation / Memory Integrity

  1. Open Windows Security

  2. Go to Device Security → Core Isolation Details

  3. Turn off Memory Integrity

  4. Restart your PC.

3. Disable VBS (Virtualization-Based Security)

Copy

bcdedit /set vsmlaunchtype off

🔍 Solution 3: Verify Hyper-V is Actually Off

Run these commands to confirm:

Copy

bcdedit /enum | findstr hypervisorlaunchtype
systeminfo | findstr /i "Hyper-V"

And in PowerShell:

Copy

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

You should see:

Copy

hypervisorlaunchtype Off

…and all Hyper-V features disabled.

🚫 Common Culprits That Keep Hyper-V Active

Even if you disable it manually, these apps can reactivate it silently:

  • Docker Desktop (using WSL2 or Hyper-V backend)

  • Windows Sandbox

  • WSL 2

  • VirtualBox (in Hyper-V mode)

  • Memory Integrity / HVCI (Windows Security)

  • Device Guard / Credential Guard

💡 Tip: If you’re unsure what’s keeping Hyper-V on, run systeminfo | findstr /i "Hyper" to spot any lingering virtualization services.
