Gates: 'customised Windows already exists'

Bill Gates conceded in court yesterday that a customised version of the Windows operating system already exists, but denied this means Windows can be configured in the way nine prosecuting US states want.

In the third and final day of Gates' stand in the witness box, he admitted that Windows XP Embedded could be classified as a "customised" version of Windows, allowing users to pick and choose certain applications, such as Internet Explorer and Media Player.

But Gates argued that the system worked differently from Windows for the home user.

Nine prosecuting US states want sanctions imposed on Microsoft to ensure that the company's Windows platform offers customers the chance to pick and choose their own applications without interoperability problems.

Over the three days, Gates has argued that any such sanctions will damage the operating system and harm the IT industry.

He also argued earlier in the week that it would not be possible to create a version of Windows with removeable features.

"I'm glad I had an opportunity to come and share my story with the court," Gates said in a statement outside the courtroom. "Microsoft has been working hard to resolve the issues in this case."

The trial, which is in its sixth week, is expected to go on into May.
