Group Policy Object (GPO) VM Migration

Overview

Some Group Policy Object (GPO) settings can interfere with driver injection, which is critical for a successful VM migration. GPO is a Windows-specific feature that manages system settings for Windows VMs. Temporarily disabling these policies ensures that driver injection can proceed reliably.

What is Affected by GPO

Driver installation cannot be done properly, leading to:

  • Blue Screen of Death (BSOD)
  • Windows VM getting stuck in boot loop
  • Migration failures due to hardware driver conflicts

What to Do

Option 1: Disable via GUI - Step by Step

  1. Open Group Policy Editor (gpedit.msc)

  2. Navigate to Driver Policies

    Go to:

    Computer Configuration
     → Administrative Templates
       → System
         → Device Installation

  3. Disable ALL restrictive policies here

    Check and set these to Not Configured (or Disabled where applicable):

    • 🚫 Critical ones (must fix)
      • Prevent installation of devices not described by other policy settings → Set to Not Configured
      • Prevent installation of devices that match any of these device IDs → Not Configured
      • Prevent installation of devices using drivers that match these device setup classes → Not Configured

Option 2: Sure Shot Way - Remove GPO via PowerShell

Terminal window
Remove-Item -Recurse -Force "C:\Windows\System32\GroupPolicy" -ErrorAction SilentlyContinue
Remove-Item -Recurse -Force "C:\Windows\System32\GroupPolicyUsers" -ErrorAction SilentlyContinue
Remove-Item -Recurse -Force "HKLM:\Software\Policies" -ErrorAction SilentlyContinue
Remove-Item -Recurse -Force "HKCU:\Software\Policies" -ErrorAction SilentlyContinue


gpupdate /force

The PowerShell method completely removes all local Group Policy settings. Use this only when GUI methods fail or when you need to ensure complete GPO removal.
