While our site focuses on WindowsXP, we often get questions about which version came first between XP and some earlier or later edition - and often we are looking up which version was when on the timeline of releases - so here for you is a great article on Wikipedia that shows the order, and if you click on a version, it goes to a page that gives much more information on that particular version  - great resource!
