Windows 10: asking for a product key

setting up new computer and it's asking for a product key.***Moved from Outlook / Windows / Classic Outlook for Windows / For business***

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.

So make sure that you are attempting to upgrade to the Home Single Language Edition. The "about" system settings screen will tell you if it is 32-bits or 64-bits (operating system):





Using the media creation tool, you want the matching 32-bit or 64-bit Single Language Edition:





From the Windows 10 ISO download site, it's just listed as Single Language Edition:





Doing an upgrade to the correct edition Anniversary Update should not ask for a product key.
