Now, exactly what does it fix?

Should I trust it?
If MS can't even provide the proper link on this page:

http://msdn.microsoft.com/vstudio/do...6/default.aspx

thats supposed to answer the question,

This article contains a list of Microsoft Knowledge Base (KB) articles about bugs that are fixed in Microsoft Visual Studio version 6.0 Service Pack 6.

Then how am I supposed to trust SP6???
