Due to an editing error, the fifth paragraph of the story, "Microsoft previews Windows 7 client OS," posted Tuesday, contained an incorrect reference to Microsoft's pricing policy for some client applications. The company says there will be no charge for these features. The story has been changed and corrected on the wire, and the fifth paragraph now reads:
Services design. The OS will focus on core capabilities and take out client applications focused on communications and user experience. Instead, these services will be offered (at no charge, Microsoft says) on the Windows Live cloud service for those who want them.
