Microsoft inches closer to Windows XP update

Microsoft late last week released an updated test version of Windows XP Service Pack 3 to about 15,000 beta testers. The update, the third such service pack for the six-year-old operating system is due out in final form in the first half of next year. The company said before its final release it expects to issue a public test version of the service pack, though it did not provide more specificity than at "a later date."
