Windows XP has more lives than your average cat. Hard as Microsoft tries to kill XP, it's the operating systems that just won't die. It's possible to buy a new PC with XP installed, fully 15 months after the worldwide launch of Vista. Lots of individuals and organizations won't go near Vista, not because of the expense it costs to upgrade, but out of naked fear that whatever off-the-shelf or custom applications they use will cease to function.

Our friends at Microsoft are masters at repudiating that which came before. Windows 3.1 was much better than 3.0. Windows 95 did all the things that 3.1 couldn't do. Same for Windows 98. On Oct. 25, 2001, little more than a month after 9/11, Bill Gates, Rudi Giuliani, and even Regis Philbin stood onstage in New York and told us that XP, the most secure operating system ever built, rendered everything before it obsolete. As for Vista, which launched in January 2007, its advantages today seem less clear cut.

If you can't kill XP, you might as well modernize it. Thus, we are about to beget Service Pack 3 for Windows XP. One of the things this service pack does is roll up the 100+ updates and patches issued since the Aug. 2004 launch of SP2 into a single, comprehensive cumulative update. For XP systems that haven't been updated regularly, this will be a good thing. The more significant benefit is an easy way to bring up to date the zillions (well, maybe not quite that many) XP systems that are being snapped up due to a widespread and acute aversion to Windows Vista. SP3 will install on any x86 version of XP: original, SP1, SP2, or systems that have had only selected patches applied. It does not support x64 editions.

In what you might consider a mild surprise, Microsoft has actually added some new under-the-hood features, perhaps an acknowledgement that XP still has plenty of life left. These new features include:

-- Improvements to black hole router detection (routers that are silently discarding packets). It will be on by default.

-- Network Access Protection (NAP), a feature introduced in Windows Vista. NAP allows better protection of network assets by enforcing compliance with system health requirements.

-- Descriptive Security Options User Interface, which provides more easily understood descriptions in the Security Options control panel in the hopes that incorrect settings will no longer be specified.

-- Enhanced security for Administrator and Service policy entries. In the System Center Essentials for Windows XP SP3, Administrator and Service entries will now be present by default on any new policy instance.

-- Microsoft Kernel Mode Cryptographic Module, a new FIPS 140-1 Level 1-compliant, general purpose, software-based, cryptographic module in the kernel mode level of the operating system.

Microsoft has issued an 11-page white paper (available as a PDF or XPS file) that provides a good overview. It should be required reading for everyone. You can find it here.

The white paper includes a one-page overview with several deployment tips.

You should download and install the latest SP3 Release Candidate on a non-production system so your tech staff can become fully familiar with it in anticipation of questions from your clients. The download is here.

It's pretty clear that XP is not going away any time soon. Not only are businesses putting off migration to Vista as long as possible (because that means new machines, since so many existing ones don't have the horsepower to properly run Vista), I still see lots of systems, especially laptops, that still run Windows 2000. It's the old concept of "good-enoughness" rearing its head once again.

We'll see SP3 released sometime in the second quarter of 2008. No complaints here. I'm looking forward to it. You should be, too.
