windows xp - Best way to retrieve license information

At my place of work, we have been given 80 computers from a company we bought out

Now these computers have office etc installed but when inventorying them, we discovered we have no literature on them about license's, serial codes etc

Is there a good piece of software which can do this, ideally over the network
