Windows 10: Problem related to product key

Split from this thread.​

hey guys my name Is Arsalan Zia a few months ago I updated my pc from window 7 to windows 10 pro but the problem I am facing is related to the product key I guess I don't have it can anyone tell me how I can get it bcz of that my windows would not activate. plz help me

:)

 

Why was I not asked for a product key when upgrading to Win 10?

According to your spec you have Win 10 Pro, but perhaps that doesn't reflect your PC.

You haven't stated which edition of Win 10 you have on this machine, nor what your Win 10 key is for.

For example, if you already have Win 10 Pro and your key is Win 10 Home, that would be a retrograde step.

product key

Hi Markese,

Thank you for using Windows 10.

I would like to inform you that if you've upgraded from a genuine qualifying activated version of Windows (Windows 7SP1/8.1), then you will not need a product key.

• Let us know if you're facing any issues with activation or product key related?

I would also suggest you to refer to the section "Will I get a product key, can I get a product key?"
