Latest Windows versions seriously flawed, vunerable

WASHINGTON -- Microsoft's newest version of Windows, billed as the most secure ever, contains serious flaws that allow hackers to steal or destroy a victim's data files across the Internet or implant rogue computer software. The company released a free fix Thursday.

A Microsoft official acknowledged that the risk to consumers was unprecedented because the glitches allow hackers to seize control of all Windows XP operating system software without requiring a computer user to do anything except connect to the Internet.

Microsoft made available on its Web site a free fix for both home and professional editions of Windows XP and forcefully urged consumers to install it immediately.

The flaws were discovered five weeks ago by independent security researchers.
