Well, it happened.
I had ordered a Windows 8.1 key a year or two ago from G2A and it worked wonderfully. I’ve been using it for a while now without any problems, but unfortunately, today, I contacted Microsoft Support.
Basically, I was going to swap my motherboard and I contacted support to make my license ready for the hardware swap. To my dismay, I was notified that my key had been activated 4 times, and blocked permanently. I basically had lost my key I spent money on because I bought it from a third party.
So… Well… If anyone has a spare key for Windows 10 Pro, I’d like to borrow it
