Thx. By the way, right after I posted my question, I found a related thread
and a guy named "garfield-n-odie" had a great suggestion about a tool from
www.belarc.com. It does a profile of your system and, among many other cool
things, retreives product keys!! So I got it anyway.

Another question while I am at it: Do you know precisely what will happen
regarding registration when load the (already loaded on XP) copy of Office
2007 onto my new Win7 partition? Will it complain? Will it just register
like normal? Dave
