This article describes how to integrate Microsoft Windows XP
Service Pack 2 (SP2) files into the Windows XP installation folder. You can use the
switch or the Update.exe utility to perform this task. These tools
help you run an in-place upgrade to Windows XP SP2 if the original Windows
Setup CD is an earlier version of Windows XP. Note
Integrating a service pack is supported only in Windows XP Home Edition and in Windows XP Professional Edition. Integrating a service pack is not supported in Windows Media Center Edition.
