Reusing W10 Home product key after upgrading to W10 Pro
A long time ago I upgraded a computer from W10 Home to W10 Pro. This was a custom build and both the original W10 Home activation and the new W10 Pro activation were done via product keys ordered from Amazon.
No Microsoft account has ever been involved with either key. Back in May of this year I completely reinstalled Windows but I don't really recall if I had to reactivate the license or not.
And now I'm wondering if I could reuse the original W10 Home product key on another computer, and if it would affect the current W10 Pro activation in any way. Would the original Home product key still be tied to my main computer's motherboard or did that history get wiped when I upgraded to Pro?
