Connor writes "The EU has announced a new wide-ranging antitrust probe into Microsoft's practices of bundling software with Windows, as well as whether its products interoperate sufficiently with competitors' products. 'The first area of investigation will concern interoperability of some of Microsoft's products, including Office 2007, the .NET Framework, and some of Microsoft's server products.' The other prong of the investigation is a response to Opera's antitrust complaint, but will look at other products, too. 'The Commission will also look at desktop search and Windows Live as well in addition to other products. The EC says that its investigation will "focus on allegations that a range of products have been unlawfully tied to sales of Microsoft's dominant operating system."'"
