What Is In Windows XP Service Pack 3
Windows XP SP3 includes all previously released Windows XP updates, including security updates and hotfixes, and select out-of-band releases. For example, the service pack includes functionality previously released as updates, such as the Microsoft® Management Console (MMC) 3.0 and the Microsoft Core XML Services 6.0 (MSXML6).
Microsoft is not adding significant functionality from newer versions of Windows, such as Windows Vista, to Windows XP through XP SP3. For instance, Windows XP SP3 does not include Windows Internet Explorer 7, although Windows XP SP3 does include updates to both Internet Explorer 6 and Internet Explorer 7, and it will update whichever version is installed on the computer. One notable exception is that, SP3 does include Network Access Protection (NAP) to help organizations that use Windows XP to take advantage of new features in the Windows Server® 2008 operating system.
