What happens to previous updates when installing SP3?

[Adam]

I am running XP Pro SP2 with all subsequent updates installed. I'm wondering
what happens to these updates when I install SP3.... does it remove them all
because they are no longer needed? Or does it see that they're there and just
install other stuff that it contains? Or what?

Thanks in anticipation!

The "updates" are in essence "hidden" and remain available should you ever
need to uninstall SP3 and revert to SP2.
