If SP3 is in your Control Panel's "Add and Remove Programs" when "Show updates" is checked, then you can uninstall it.
If not, this means that XP was installed from an SP3 boot media, so you need to follow ~quack's advice.
I am trying to upgrade/downgrade to an earlier version of XP Pro Sp2. Yogesh Service Packs are basically one-way installs - they change/modify too many things to be undone safely.
