They won't give us an answer we can only guess and its safe to say at
this point, MS is abandoning the newsgroups in favor of web-based
forums. How long this server has to live? Anyone's guess but I suspect
it will be less than a year, and they will pull the plug on it.
If so, not a major loss, because most of the most popular newsgroups
here are already carried on other servers and will continue. Usenet
doesn't rely on Microsoft for anything. Hosting customized support
newsgroups is common but not required.
On the other hand, the website might be an experiment, and it might
prove inefficient and unpopular. There's no reason MS can't change their
minds and create new newsgroups later. The original MS help site was
just a web interface to these groups.
Alternatively, there really doesn't seem to be much difference between
Vista and Windows 7, except the eye candy and a few tweaks, so this
might be the newsgroup for the best help.
