ProduKey
When you install Microsoft Windows or Microsoft Office, you are typically asked for a CD-Key. It's the code that you find on a label on the software's packaging. What happens if you have to reinstall Windows or Office but you've lost the packaging or the label is torn off? Simple. Use Produkey.
ProduKey is a small utility that allows you to see the product key or CD-key of Microsoft products. Just download and launch Produkey to see the various serial codes. Copy them somewhere safe so that you can use them as necessary. Produkey will only allow you to see the installation codes of various programs. It won't generate new codes.
ProduKey works on all 32-bit versions of Windows, though there is a special 64-bit version as well. You can find installation codes for Windows 95, 98, 98 SE, 2000, ME, NT, XP, Vista, Server and Office 97/2000/2003/XP/2007.
