Hi,
If you’re looking to upgrade from Windows 10 Pro to Windows 11 Pro silently without using SCCM or Intune but it is important to note that Group Policy alone can’t handle the entire upgrade process. However, you can achieve a fully automated upgrade by combining a custom script, the Windows 11 ISO, and GPO deployment.
You can download the official Windows 11 ISO from Microsoft here: Download Windows 11
Once you have the ISO, you can deploy the upgrade script using Group Policy:
- Open Group Policy Management on your Windows Server 2019.
- Create or edit a GPO linked to the OU containing your target machines.
- Navigate to: Computer Configuration > Policies > Windows Settings > Scripts (Startup/Shutdown)
- Select Startup, then add your script. You can copy the script to \DomainController\SysVol\YourDomain\Scripts\ and reference it from there.
This approach allows the upgrade to run silently in the background with minimal user impact.
Hope this helps!
