"DEFAULTS. Microsoft will design Windows in a way that enables computer manufacturers and users to set non-Microsoft programs to operate by default in key categories, such as web browsing and media playback, in lieu of corresponding end-user functionality in windows. computer manufacturers are free to set these defaults as they please when building new personal computers.

APIs. Microsoft provides the developer community with a broad range of innovative operating system services, through documented application programming interfaces (APIs), for use in developing state-of-the-art applications. The U.S. antitrust ruling requires that Microsoft disclose all of the interfaces internal to Windows called by "middleware" within the operating system, such as the browser, the media player, and so forth. In this way, competitors in these categories will know that they can plug into Windows to get services in the same way that these built-in Windows features do. This has worked well, and Microsoft will continue to disclose these interfaces even after the U.S. antitrust ruling expires. In fact, we will go further, extending our API commitment to the benefit of all software developers. Going forward, Microsoft will ensure that all the interfaces within Windows called by any other Microsoft product, such as the Microsoft Office system or Windows Live, will be disclosed for use by the developer community generally. That means that anything that Microsoft products can do in terms of how they plug into Windows, competing products will be able to do as well."
