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

WinKeyFinder is free and portable.


Try using Magical Jelly Bean keyfinder. It should help you find the PC licenses. Here's a bit of information on the app, from the creators website:

The Magical Jelly Bean Keyfinder is a freeware open source utility that retrieves your Product Key (cd key) used to install Windows from your registry. It allows you to print or save your keys for safekeeping. It works on Windows 95, 98, ME, 2000, XP, Vista, Server 2003, Server 2008, Office XP, Office 2003, and Office 2007 family of products. It also has a community-updated configuration file that retrieves product keys for many other applications. Another feature is the ability to retrieve product keys from unbootable Windows installations.


Unfortunately, unless you have license documentation microsofts point of view will be that you're not licensed regardless of what codes you have.

This page gives relevant information


Generally unless you have the certificate or some sort of evidence of a license transfer you don't have a license.

  • Is there documentation to back this up? – pave Sep 18 '09 at 11:03
  • Nope. – alex Sep 18 '09 at 11:15
  • This is correct and should have been handled as part of 'Due Diligence' when buying out a company and transferring its assets to yourself. During an external audit you will need to provide proof of purchase, certificate of authenticity and a valid code. As we all know, valid codes are 10-a-penny on t'internet, as so do 'they' – Szetak Sep 18 '09 at 12:50
  • +1. Product keys are the technical side of license enforcement but they can be worked around and will not convince an organisation like the BSA if they check you out (even WGA/OGA is not enough). Without the legal side of actual inventoried licenses you have no guarantee that the previous company didn't just rip the software off. Best reinstall under your own volume licensing, or else replace with alternatives. – bobince Sep 18 '09 at 12:59
