Newsgroups hosted by Microsoft's private news server (msnews.microsoft.com) are a good source of online help. It's peer-to-peer support, so it's the user community that supports each other, although there are individuals who answer enough questions that Microsoft rewards them by designating them as MVP's (Most Valuable Professional).
There are two ways to access these news groups: with a news reader (e.g. Outlook Express) or a web interface.
Warning: there are a LARGE number of newsgroups here! Subscribe to the ones that you are interested in. You will most likely be interested in groups like: microsoft.public.windowsupdate.
Newsgroups are listed in the left frame. The "microsoft.public" part of the newgroup names are not displayed here, so newsgroups appear as: "windowsupdate" instead of "microsoft.public.windowsupdate".
