It looks like Hyper-V is already running.

One of the most common issues currently happening.

Understanding the Problem

The Software checks:

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

2. The hypervisor signature is "Microsoft Hv"

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

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

Solutions (in order of recommendation)

Final Solution: HyperV Disabler batch file

What does this do? It is quite simple.

It simply renames the core hypervisor executables from Windows (hvix64 and hvax64, based on case Intel or AMD) to hvix64_old and hvax64_old which will ensure any active Hyper-V layer is completely disabled. RunAsTI snippet to run as TI/System, with innovative HKCU load, ownership privileges, high priority, and explorer support. This solution should work 100%. Don't forget to run the batch file as admin.

Solution 1: Disable Hyper-V Completely

This is the most reliable solution if you don't need Hyper-V:

Method A: Using Windows Features

1. Open "Turn Windows features on or off" (search in Start menu)

2. Uncheck these items:

   • 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: Using Command Prompt (Run as Administrator)

CMD (Batch)

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

Then restart your PC.

Method C: Using PowerShell (Run as Administrator)

PowerShell

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

Restart required.

Solution 2: Check for Hidden Hyper-V Services

Even with Hyper-V "disabled," some services might still activate the hypervisor:

1. Disable Windows Defender Application Guard:

CMD (Batch)

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

1. Disable Core Isolation/Memory Integrity:

   • Open Windows Security

   • Go to Device Security → Core Isolation Details

   • Turn off "Memory Integrity"

   • Restart

2. Check for VBS (Virtualization-Based Security):

CMD (Batch)

   bcdedit /set vsmlaunchtype off

Solution 3: Verify Hyper-V is Actually Off

After disabling, verify with these commands:

CMD (Batch)

# Check hypervisor launch type
bcdedit /enum | findstr hypervisorlaunchtype

# Check if virtualization is enabled
systeminfo | findstr /i "Hyper-V"

# PowerShell check
Get-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

Should show:

• hypervisorlaunchtype Off

• No Hyper-V features listed or all showing "Disabled"

Common Culprits That Keep Hyper-V Active

Even after "disabling" Hyper-V, these can reactivate it:

1. Docker Desktop (if configured for WSL2 or Hyper-V backend)

2. Windows Sandbox

3. WSL 2 (uses Hyper-V infrastructure)

4. VirtualBox (with Hyper-V mode enabled)

5. Memory Integrity/HVCI (Windows Security feature)

6. Device Guard/Credential Guard
