Windows Update

Hi

This is not a new PC, and Windows Update has worked many times in the past.
It's a 3GHz P4 running WinXP-pro SP2.
When I try a Windows Update I get redirected to this page:

http://www.update.microsoft.com/wind...&thankspage=2&

"Thank you for your interest in obtaining updates from our site.
This website is designed to work with Microsoft Windows operating systems
only.

operating systems, please visit http://www.microsoft.com/mac/. "

Why? I have disabled all firewalls, I don't run Norton, and am using IE7.
I've checked the knowledge base on micorsoft.com, but found nothing.

Ah, problem sorted.
It was related to these keys:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \
Internet Settings \ 5.0 \ User Agent

and

HKEY_CURRENT_USER \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \
Internet Settings \ 5.0 \ User Agent

But not in the \5.0\ key.

Don't know why this happened though.
