Can You Retrieve Your Office XP Serial Key?

I am trying to carry out a software audit at work. We have an open licence for both Office XP Upgrade and Office XP Full Version. We also have several licences tied to specific PC?s.

Is there way to retrieve the serial key information on each workstation, so that I can check that not only the machines have the correct licence, but also that I haven?t gone over the limit on the open licences?

I hope its alright posting to this group, but I couldn?t find an Office XP one.
