Here for everybody, AppNee collected almost the every Product Key (also called installation serial numbers) for all editions of Windows 7. They are manifold but not disorderly mixed, because I have tried our best to make them orderly, maybe still need you to pay some patience when finding. For AppNee, I have a performance list for Windows Pro Editions, that’s: 98 > XP > 8.1 > 7 > 8 > 10 > Vista. I guess for many guys who pursue the performance and have tried Windows 8/8.1 or even the latest Windows 10, they found they like Windows 7 better, or even want to change back to Window 7.
