I am trying to fix a computer for a friend that was dug out of storage and the password forgotten. After I couldn't reset the password or otherwise gain access to it, I decided to reformat and install the OS fresh. Upon installation, the product key on the side of the computer is invalid. There are two CoAs on the computer, one, seemingly the original, that is marked DO NOT USE, and another that is marked refurbished. I tried the serial on the refurbished sticker first, but neither one works.
I read somehwere in the endless sea of nonsense about such an issue, and one theory was stated as Microsoft 'negated' the refurbished product keys for some reason or another. The thread was so old that the link provided as proof didn't work anymore.
Anyone have any idea what's going on here? I believe I may have bricked this apparatus.
