How to uninstall Windows XP service pack sp3

[Jeanie]

I need help.. I searched for updates and it installed a service pack sp3 for my windows xp perfessional. I was looking for updates to excel and now i can not even open excel because it wants to install and ask for the cd, when i place the cd in it still says it is the wrong program. How do I get rid of it...?
Thanks in advance...

Place the Excel or Office CD 1 in the CD drive, and select repair from the installation menu. Updates will need to be reinstalled.

By the way, Windows XP SP2 is barely in beta; that was Office SP3 you installed. You should probably only have WinXP SP1.
