Windows 10: Updated my motherboard and now can't activate Windows 10

Hi I got a new motherboard install yesterday and now windows is looking to the product key. I've never seen the product key as Windows 7 came with the computer and then got the free upgrade to Windows 10. How do I find my product key?

:)

 

Windows 10 will not activate Error code 0x803F7001

thanks
I activated my Windows 10 from product key Windows 7

 

Windows 10 Activation (Insider)

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.

 

Windows saying not activated after motherboard upgrade

Hi,

I recently upgraded some PC parts (new motherboard, RAM, processor, video card) and ever since then I have a watermark in the bottom right of my display reading "Activate Windows - Go to Settings to activate Windows."

I took advantage of the free upgrade to Windows 10 back when they were allowing Windows 8 users to upgrade to Windows 10. I don't remember receiving an activation key during this upgrade.

I've read online that installing a new motherboard can occasionally cause issues with OS activation. How can I reactivate my Windows without having to purchase Windows 10.

Some things to note:

• This watermark was not there prior to installing the new motherboard
• As some places (and a Microsoft Tech Support member) suggested, typing the query "wmic path softwarelicensingservice get OA3xOriginalProductKey" into CMD just returns with "OA3xOriginalProductKey". The Microsoft Support member seemed confused by this and said there was nothing further she could do.

Thanks!
