Most Firms Face Security 'Red Alert' as XP SP2's Retirement Looms

Computerworld: A new report by vendor Softchoice Corp. says that 77 percent of businesses run Windows XP service pack 2 (SP2) on 10 percent or more of their PCs. What's the big deal? Microsoft will stop supporting the operating system after July 13, meaning that those users will no longer receive security updates and may become vulnerable to threats.

"This is a red alert," said Softchoice's Dean Williams. "This isn't something you can safely ignore, like you might have before."

Windows XP SP2 users are encouraged to upgrade to SP3 as soon as possible.
