Windows XP Fans, Your Christmas Present Has Arrived

A Different "RC" Flavor: Windows XP SP3!

Need some diversion after the last present is opened and the last piece of candy from the stockings have been devoured? Give Windows XP SP3 RC a try. It's a 336MB download.

Roll Up the Updates

SP3 rolls up all previously-released updates into a single package. Microsoft's documentation for SP3 highlights just a few you might have missed (but your system administrator probably didn't):

• Microsoft Management Console 3.0 (KB907265)
• Microsoft XML 6.0 Microsoft Windows Installer 3.1 (KB907265)
• BITS 2.5, a service used by Windows Live OneCare and Microsoft System Center Configuration Manager 2007 (KB923845)
• WPA2 Wi-Fi Security, the strongest form of WPA security (KB893357
• Peer Name Resolution Protocol 2.1, to enable XP SP3 programs that use PNRP to communicate with Vista programs that use PNRP (KB920342)

Other bundled updates include changes to IPSec virtual private networking and a new service for logging into domains (DIMS).

SP1 Users, Rejoice! SP3 Includes SP2 (and SP1)! 

Windows XP SP3 includes both SP1 and SP2, so if your system's been under a rock and missed SP2 (or if you're doing a fresh install from an original Windows XP or XP SP1 disc), you can install SP3 anyway. However, you must have SP1 installed to use SP3.

Here's What New in SP3 (Not a Whole Lot, to Be Honest)

SP3 adds the following new features:

• "Black Hole" router detection is enabled by default
• Support for Network Access Protection (NAP), a feature in Windows Vista and Windows Server 2008
• The Security Options dialog in Control Panel now includes an "Explain This Setting" tab to help keep you from making security setting goofs.
• Enhanced security for Administrator and Service policy entries in System Center Essentials
• New kernel mode Cryptographic driver
• No product key needed for SP3 installation; it's requested after installation

Microsoft's been warning XP SP2 users that SP3 wasn't going to include a lot of new functionality - and they were right. Most of the changes in SP3 are not going to be visible to end-users.

I've Got XP x64! Where's My Update?

Windows XP SP3 is for 32-bit versions of Windows only. x64 users should install Windows Server 2003 SP2, which has been around awhile (over a year, in fact).

For More Information

As usual, Microsoft has lots of documentation you can grab, including

• Windows XP Service Pack 3 Overview, available in your choice of Adobe PDF or Microsoft XPS formats
• Release Notes (KB936929)
• The Windows XP SP3 RC page has links to the RC download and to the what's new white paper listed above.

Just a reminder: this is the Release Candidate, so it's a step better than beta, but it's not quite ready for prime time. You might want to try it on the experimental box, not your deathmatch special.
