Step 1: Disable Hyper-V Features

  1. Open the Start menu, type Turn Windows features on or off, and press Enter.
  2. Uncheck the following boxes if they are enabled:
    • Hyper-V
    • Virtual Machine Platform
    • Windows Hypervisor Platform
  3. Click OK and restart your computer.

Step 2: Run the Complete Hypervisor Wipe Command

Even if features are unchecked in Windows Features, Windows 11 Pro can keep a silent hypervisor state running.

  1. Right-click the Start Button and select Terminal (Admin) or Command Prompt (Admin).
  2. Type the following command to completely disable the Microsoft hypervisor at boot: 
    bcdedit /set hypervisorlaunchtype off
  3. Press Enter. You should see “The operation completed successfully.”

Step 3: Perform a Full Cold Reboot

A normal “Restart” in Windows 11 often uses “Fast Startup,” which hibernates the kernel and preserves the hypervisor state.

  1. Close all open applications.
  2. Open your Command Prompt/Terminal again and run: 
    shutdown /s /t 0
  3. This forces a complete shutdown. Wait for the computer to power off fully, then turn it back on.
