Good job. You wrote "War and Peace" without answering the
OP's question. If you have reformatted your HD and have
no access to the product ID, and no proof of purchase,
you're screwed. If, on the other hand, you have not yet
reformatted the drive the information can be retrieved,
and I believe that if you have proof of purchase MS will
give you a new number.
