Given your description of what happened I would be suspicious of some sort of malware on your system.
Updating windows components with any connection whatsoever to internet access on an infested system can screw things up badly. The problem is that such programs like to hide themselves deep in the stuff Windows uses to access the internet and when Microsoft's installer blindly replaces a file that has been tampered with the result can be a big mess.
I've hosed a system badly enough to need to format/reinstall by installing the Internet Explorer 6 update without realizing the system was infected.
What are you using for a firewall, anti-virus and anti-spyware?
