Could you elaborate on this a bit more? So that we have a common understanding of what you have.
- Can you briefly explain what you have purchased? Perhaps the specific Microsoft license and also service?
- Can you also briefly explain who / how you purchased it ? Essentially whether you purchased it from Microsoft website, or a 3rd party reseller website
- Is the premium service offered by Microsoft? or was it a service provided by the reseller?
This context is important so we can advise you where you might have to go for the support?

Dear Hermann Strebel1,
Good day! Thank you for posting to Microsoft Community.
To answer your question, the Microsoft 365 Business Premium subscription does not include a full Windows 11 license. However, it does include the ability to upgrade Windows 10 Pro devices to Windows 11 Pro. If you have Windows devices running Windows 7 Pro, Windows 8 Pro, or Windows 8.1 Pro, your Microsoft 365 Business Premium subscription entitles you upgrade those devices to Windows Pro 10. However, the Microsoft 365 Business Premium does not include free upgrade rights from Windows 10 or 11 Home to Windows 10 or 11 Pro. You can refer to Upgrade Windows devices to Windows 10 or 11 Pro - Microsoft 365 Business Premium | Microsoft Learn
Regarding the issue with the Windows 11 Home devices, it is possible that the generic Windows 11 Pro key you used to upgrade the devices is not valid or has been blocked by Microsoft. Also, the error code 0xC004C003 occurs when a licensing code component tries to access a registry hive without proper access. A resulting access denied error causes the product key not to be extracted correctly. This could be the reason why the devices are showing the error code. Therefore, to activate Windows 11 Pro on these devices, you will need to purchase a valid Windows 11 Pro license. Once you have a valid license, you can use it to activate Windows 11 Pro on the devices and then perform the Azure AD join via Entra ID.
I hope this helps! Let me know if you have any further questions or concerns.
Thank you for your precious time. Have a nice day.
Sincerely,
