>There is good reason for the GUID. Several years ago, Microsoft kept moving content around and breaking links (primarily to KB articles) that others had made. Several years in a row, this issue was raised to Microsoft executives at the MVP Summit. The GUIDs, while inconvenient, fixed the problem.

Lots of links here bring to the page that has been moved. But luckily you're re-directed to the proper place when clicking on such links.

But in articles I often see a warning that links may be broken. I don't think I've checked if they indeed are broken.
