Dear Neil Abadie,
To facilitate the upgrade from Windows 11 Home to Windows 11 Pro, you can use the following generic product key provided by Microsoft for evaluation and upgrade purposes:
VK7JG-NPHTM-C97JM-9MPGT-3V66T
Please note: This key will allow you to upgrade the edition but will not activate Windows. Activation will occur once the device is licensed through your Microsoft 365 E5 subscription and properly joined to Microsoft Entra ID or managed via Intune.
- Upgrade from Home to Pro using the generic key Go to Settings > System > Activation > Change product key Enter the generic key above to initiate the upgrade
- Apply Enterprise license via Microsoft 365 E5 Ensure the device is Microsoft Entra-joined and the user is assigned a valid E5 license Windows will automatically upgrade to Enterprise edition and activate once connected to the internet
- Verify Activation Status After upgrade, confirm activation under Settings > System > Activation
