No, Windows XP Service Pack 2 includes Service Pack 1 and it's a direct replacement for Windows XP Service Pack 1. Service packs are cumulative. This means that the problems that are fixed in a service pack are also fixed in later service packs. For example, Windows XP SP2 contains all the fixes that are included in Windows XP Service Pack 1 (SP1). You do not have to install an earlier service pack before you install Windows XP SP2.



Similarly, you don't have to uninstall Windows XP Service Pack 1 before installing Service Pack 2.
