Totally agree! Must remember that most of us already have SP2 with basically every single update, so logically installing the SP3 would be worse off seeing as it is missing components and updates available beyond SP3, regardless of its extra features.
SP3 should be used upon the next format. As stated by Microsoft, it is a collection of a greater portion of updates made available from SP2 till now + added security features and ' read the white paper '.
Please note that removing every single update from the add/remove section, and getting XP back to basic SP2 standard and then installing SP3 is foolish, but i had to try it anyways. Dont do it.
