I have wondered about what would happen under such circumstances. What a boondoggle the "rightful" owned my end up being involved in. And, so many could be trying to use the same key. I would think the key would have to be invalidated eventually by MS. I am not sure how the "rightful" owner would go about establishing his or her right to the key (i.e., to a replacement key)--except by demonstrating possession of the original disk. |
