I spent most of the day on hold and being bounced around with Microsoft and was told to call Lenovo because it was an OEM issue.
I just upgraded from 8.1 to 10 and when I try to enter my product key it says it is being used by another computer. Microsoft says I need to contact lenovo because my product key is fine but it is an OEM issue. Lenovo is saying that because I went from 8.1 to 10 it is causing issues because my laptop was shipped with Windows 8.
So my question is how can I keep 10 but and activate it? Do I need to reinstall 8 then come back to 10? And can I come back to 10 now being that the free upgrades are over.
Can it be done or do I just go back to 8.1?
Appreciate any and all help
