Windows 10: Cant activate Windows 10 Pro on apparently "pirated" Windows 10 Enterprise N

Hi everyone! For the past couple of days I have been trying to activate a windows 10 Pro license key on my windows 10 enterprise n pc. But whenever i try activating it I am greeted with the following error: I have led multiple "investigations" on the problem and I have found out that the PC shop where my desktop Pc was assembled 2-3 years ago had activated my windows but not in a legitimate way. Please help I have tried everything including troubleshooting methods in command prompt and other ways. All I want is an original windows 10 license on my pc before I upgrade to windows 11. I will off

:)

 

Windows 10 Activation (Insider)

I bought Windows 7 Pro OEM key from G2Play.net for 12€ to upgrade to Windows 10 Pro - worked like a charm but be advised if you buy a OEM key you can not download the Win 7 iso from microsoft and have to get it elsewhere.

A Windows key for just 12 Euros? That's pirate then.

 

Windows 10 pro

I need to change my motherboard, have windows 10 pro. When i google how to it says go to activation then add an account, my issue is there is no add an account option under activation? Or am I in the wrong window?



Not sure how to proceed, ive googled it and the same results. Do I have an OEM or? On the disk sleave it says OEI DVD?
The COA says windows 10 pro for OEM software
