why does it ask

[jeff]

I recently tried out office 2007 and i like it but it is such a resource hog
that i went back to office 2003 so i uninstalled office 07 rebooted and then
installed 03 now MS updates are saying that a security update is needed for
office 2007 when i just uninstalled it?

The reason that happens as you describe is because you did not uninstall Office 2007
completely.
