Hello everyone: for some time now I have been unable to do manual or auto microsoft updates. When I attempt to access the update site via the web I get a message that the site is designed for windows based systems only and I should visit the MAC site for further information. This implies that my system is being seen as a non valid XP Operating system which of course it is. Called Microsoft and their canned answer was to uninstall WINXP and reinstall which I have done including SP2 with exactly the same results. I have tried a great number of tricks including several free and paid versions of Spyware. Have tried doing an SFC scan now etc. etc. with no luck. I have no problems getting into the web or communicating wirelessly or in fact using the laptop as is. I really don't want to low level this system and start from scratch unless I absolutely have to. ANY IDEAS ! ! ! Thx sincerely.
