Why do some sites, including Microsoft sites, come back stating that I am running XP on this machine when I am not?

This has been happening for some time now, and Microsoft was less than helpful when I posed the question to them. Is it a browser issue, or something in the registry? I don't really know where to begin searching.

Please help!
