Windows XP 'ready for production by Friday'

Microsoft's chief executive has announced that Windows XP should be ready for production by the end of the week.

Steve Ballmer told a news conference in Sao Paulo this means the new version of the operating system is on track for its scheduled October release.

The announcement strikes a note of defiance after Microsoft lost an appeal to delay the final outcome of its anti-trust lawsuit.

Last week's ruling paves the way for the district court to quickly decide a new penalty. Opponents are pressing for any new measures to include a block on XP because they claim it combines features that could stifle competition.

The software has come under fire from competitors angered at the inclusion of instant messaging, digital photography and personal firewall applications.

But Mr Ballmer has played down the ongoing controversy, arguing that Microsoft is eager to settle the anti-trust case, but should continue to produce products in the mean time.

"Our job now is to get Windows XP done," he told the meeting of Brazilian tech executives. "With a little bit of luck, we should have it ready by Friday."

Mr Ballmer has also dismissed allegations the company is indulging in any anti-competitive behaviour, saying: "I don't know what a monopoly is until somebody tells me."
