Note: All of the addresses of the KB / Articles - 2007 Products / MS / Non-MS Articles below were valid at the time I added them to the WSS FAQ site and to this file. I can't guarantee that they still are.
(You will find new items more quickly by checking at wssv3faq.mindsharp.com as this post is irregular because of the lack of new material on these back products.)

NOTE: Amendments to KB articles are now only listed when a version is x.0. MS no longer change the dates of KB articles when version changes are minor.
