Microsoft put windows 8 evaluation copy build something when it was windows8.1 what does this mean?
Microsoft didn't do anything, you or your repair person did. Evaluation copy means that you don't have a legally licensed copy of Windows on there. If you bought the computer like that, return it for a full refund. If you took it to a repair place to fix something like a broken motherboard or disk, go back and demand they give you a proper license.
