Re: Battlefield 3 Activation key is lost
I actually had this very issue on my second gaming PC after updating it to WIN10. What I did was right click the BF3 icon in my games library and selected to run a repair. I allowed the repair to finish, reloaded my library games by clicking on the top left menu "origin" and then "reload my games" and then I logged into battlelog and joined a server. Origin did not ask me for a key again.
