XP SP3 Coming April 21 for OEMs, MSDN/TechNet Subscribers

With Windows Vista taking quite a bit of heat from customers and pundits around the web, many people have looked to its elder brother -- Windows XP -- for solace. The nearly seven-year-old operating system still soldiers on for many and is seen as a relatively "lightweight" and better-performing alternative to Windows Vista.

However, with Windows XP showing more than a few gray whiskers in its beard, it's important to at least keep the operating system somewhat relevant in today's world. Service Pack 3 (SP3) promises to give Windows XP a nice caffeine boost to allow it to stay fresh for at least a few more years.
