determining Office product key

[chachie]

I have two copies of MS Office in front of me (with
intact product keys). What I need to know is which one
is loaded on my machine vs. the one loaded on my
father's? How can I find the product key for the copy
installed on my machine?

google around, there are many utilities you can use to find out your 5x5
key, like aida32 for one (awesome utility for MUCH more than just license
inspection).
