Windows 10: Updraded to Windows 10 Pro -- now my windows isn't activated

Hi,


I'm getting an activation error, 0xC004F213. It says that no product key is on my device. This happened about 1 day after I upgraded to Windows 10 Pro and turned on Bitlocker encryption.


I am using an Asus UX305F, which came with Windows 8 installed. I upgraded to Windows 10 home for free during the period when upgrades were free. My windows was always activated during this time and I logged in using a microsoft account every time I used my computer.


I've tried the activation troubleshooter to no effect. I've tried looking for my product key (using suggested commands and programs), and have found one, but entering it doesn't fix the problem. My Microsoft account has a record of my purchase of the Pro upgrade, but it seems to have conveniently forgotten that I ever owned Windows 10 home.


Is this something I need to worry about?


Thanks,


Steve

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.

 

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

How long did you wait for activation?
When I re-installed with a fresh install... it took a few hours to sync and activate.
However, it did, finally, activate.
