Windows XP Service Pack 3 (XP SP3) fixes a range of bugs and adds new features to
Windows XP. The file is a large download and can be applied to any version of Windows XP Home, Professional, TabletPC or Media Center (32 bit only). In addition, it doesn't matter what XP patches you have previously applied to your system, SP3 will update any unpatched, partially patched or completely updated system to version SP3. It includes all features of Service Pack 1 and 2, plus all patches, updates and fixes released up to and including April 2008's monthly security bulletin. Keep in mind that new patches made available after Service Pack 3 was released (mid April 2008) will still need to be applied.
Important notes: Microsoft advise uninstalling any beta or Release Candidate versions before installing this final release. Do not install Service Pack 3 on systems with AMD chips unless a special hotfix has been applied first. This hotfix needs to be applied before SP3, otherwise your system may get stuck in a loop and never start.

The advantage of this full download is that it can be used on any system - plus it doesn't require an Internet connection to install. You can download SP3, copy it to disc or a portable drive and use it on multiple PCs. Alternatively, since the file is so huge, you can download SP3 on a fast Internet connection and use it to update a PC with a slow or non-existent connection.
Windows XP Service Pack 3 (SP3) includes the following:
* All previous security patches and fixes released for Windows XP.
* All enhancements and new features that were included with Windows XP SP1 and Windows XP SP2
* Only two new features have been added: Black Hole Router Detection Windows and Network Access Protection (NAP).
* The following are already available for Windows XP in stand-alone updates. Windows XP SP3 includes them by default (System administrators must choose to install each of these updates): MMC 3.0, MSXML6, Microsoft Windows Installer 3.1 v2, Background Intelligent Transfer Service (BITS) 2.5, IPsec Simple Policy Update for Windows Server 2003 and Windows XP, Digital Identity, Management Service (DIMS), Peer Name Resolution Protocol (PNRP) 2.1, Wi-Fi Protected Access 2 (WPA2).
* From the Release Notes: "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)."
