How to download windows 11 23 H2 for enterprise and activate the OS with Microsoft 365 E3 License

Hi Vishakhan,

Normaly when your users with a Microsoft 365 E3 License assigned login to the computer via Entra ID (Entra ID joined device/Intune), the Windows edition should be upgraded automatically.

Here is the right docs on this: https://learn.microsoft.com/en-us/windows/deployment/deploy-enterprise-licenses?pivots=windows-11#assigning-licenses-to-users

Just take note of this:

Windows Enterprise E3 and E5 are available as online services via subscription. Windows Enterprise can be deployed in an organization without keys and reboots.

• Devices with a current Windows Pro edition license can be seamlessly upgraded to Windows Enterprise.
• Product key-based Windows Enterprise software licenses can be transitioned to Windows Enterprise subscriptions.

Organizations that have an enterprise agreement can also benefit from the service, using traditional Active Directory-joined devices. In this scenario, the Active Directory user that signs in on their device must be synchronized with Microsoft Entra ID using Microsoft Entra Connect Sync. So - if you upgrade it via etc. a Windows 11 Pro .iso (available here: https://www.microsoft.com/software-download/windows11) then your users sign in, the edition should be automatically upgraded if meets the above :)

If this is helpfull, place vote or mark as answer.

@Michael Morten Sonne Thanks for your response, We have licensed Windows 11 21 H2 ISO image, but we are setting up new domain and we need to deploy all end user devices with Windows 11 23 H2 Enterprise edition. Also we may need to deploy OS via WDS and SCCM PXE.

So i have downloaded the ISO image as you mentioned above and installed Windows 11 Pro 23H2 version (available here: https://www.microsoft.com/software-download/windows11) but when i sign in with our E3 Licensed Entra ID, the OS is not converted to Enterprise edition. Its still in Windows 11 Pro Edition. Also tried this method with Windows 11 23 H2 Enterprise Evaluation version. But no luck. Could you please confirm in this scenario how can we proceed with a convenient method to fulfill our requirement.
