In that case, maybe it’s not such a good idea… although it does leave you very vulnerable to infection.
I suggest you switch to Opera or Firefox straight away, because an old version of IE will be full of holes, and will expose you to auto-installing spyware.
I did read about a site where you can download Windows updates without the Genuine Advantage check, but I can’t remember where. Maybe you could Google for it and search the forum.
Maybe somebody will read this and post a link.
Glad you problem is solved, anyway.
EDIT: I think this was the site:

NB: Requires Firefox
