I have an XP machine with Office 2007 installed. I just loaded Win7 in a new
partition and plan to install same copy of Office in the new partition (I am
led to believe this is OK and doable).

Question: I have two office 2007 DVDs; how do I figure out which one I
previously installed on this machine? I can get Product ID from registry,
but I cannot find a way to match the Product ID to anything (like the Product
Key) on the box. Dave
