SP2 supercedes SP1 in its entirety. After installing SP2,
visit the Windows Update web site for any additional
post-SP2 critical updates.
This article lists the problems that are fixed in Microsoft Windows
XP Service Pack 2 (SP2). 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).
