KeyFinder Thing is a simple utility to retrieve the Serial numbers or CD Keys of Microsoft software installed on your system.
It includes options to export the list of found keys and a search option to find keys not included by default.
It can retrieve Microsoft VISTA & Office 2007 keys also.
Its smaller! (30 kb) Its Faster! Its basic and to the point now and the only dependency is MSVBM60.dll (The VB6 Runtime that most people have anyway these days.)

Magical Jelly Bean Keyfinder is another good one

It allows you to change the keys also.
