For example: Windows XP RTM ---> Windows XP Service Pack 3 Windows XP Service Pack 1 ---> Windows XP Service Pack 3 Windows XP RTM ---> Windows XP Service Pack 2 Service Pack 3 is the latest service pack for Windows XP; any planned updates should be to this service pack, and not an older one. As per above, you do not need to install any previous service packs before installing Service Pack 3.
If you have Windows service pack 3, then you need to download SP3 Drivers. If you have Windows Service Pack 1, then you need to download SP1 Drivers.
