I find the bsalsa EmbeddedWB Home interesting, as it is not something I have seen before. I would check your installation of IE to make sure there are no unexpected addins running. You might want to download Windows Defender from the Microsoft web site (use firefox to do it). The program is not as good as when it was in Beta, but it does have a nice tool for checking the registry associated with IE to find Browser Helper Objects, which are added libraries that you might not be expecting to run, which could affect your ability to browse the web.

However, your browser does appear to identify itself correctly according to the spec you listed. Another possiblility is that something is preventing a script or a applet from running when you visit the update site. Just to be sure, you could try temporarily suspending your AV and firewall while connecting to the site to see if it works (as long as you are behind a hardware firewall such as a router, and make sure the Windows firewall activates) that way.
