my Windows digital license

2026-11-13T06:56:35.72+00:00

Hello. I need help recovering my Windows digital license.

I originally had a genuine Windows 8 Pro license on this same computer. I later upgraded to Windows 10, and I believe it was digitally activated.

I am now running Windows 11 Pro on the same PC. Windows is not activated and reports error 0xC004F034.

The installed edition is Windows 11 Pro, Retail channel. The system currently shows the generic Windows Pro installation key.

I no longer have the original Windows 8 product key.

Could you please check whether my original Windows 8 Pro license was converted into a digital entitlement and whether it can be restored for this device?

I do not want to purchase another license if my original digital entitlement is still valid.

Thank you.

    Hi, if your Windows 11 licence is based on a previous Windows 8 licence, that is causing the activation errors, Microsoft changed the licensing rules a while ago and after they changed the rules, they have blocked a Windows 7 and 8 product key form activating Windows 10 or 11 on new hardware.

    If you have not changed your motherboard or PC, this forum is just a user to user forum, you will need to contact Microsoft Support directly to ask them to reactivate your Windows licence.
