The EU fines levied against Microsoft won't affect the launch of Windows Vista, according to a Microsoft executive.

On Wednesday, the European Commission fined Microsoft €280.5 million for failing to comply with the terms of a March 2004 anti-trust judgment against it.

As part of the judgment the company was ordered to provide competitors with technical details of communication protocols used by its server products. The fine was imposed to punish Microsoft for failing to do so in a timely manner.

"What the EU wanted was not that specific until April. We agreed to a set of milestones and we're hitting those milestones but the last milestone is a week or so away," said Darren Huston, president and chief executive officer of Microsoft's Japanese unit.

The fine will not impact the launch schedule for Windows Vista, said Huston. The company's new operating system is scheduled to be available through volume licensing in November and through retail to consumers in early 2007.

The OS is already in beta testing. At this stage the biggest threat to the schedule would come from a beta tester finding a serious problem in the software that would require significant amounts of work, Huston said.

However, as the release date approaches the probability of finding such a flaw decreases because it would likely have been caught already, he said.
