Microsoft Antitrust Case Antitrust Practices and Market Power

Antitrust case: 2001 antitrust Microsoft settlement

All Windows' features, from point-and-click icons to software for sending faxes from a personal computer, were once sold as separate products" (Lohr 1998, U.S. v. Microsoft). The bundling reduced competitive practices while Microsoft said that designing its operating system as it did was its right as a company.
In the eventual settlement between the government and Microsoft, Microsoft had to share information with third parties to enable them to more easily create browsers that would be just as compatible with Windows as Internet Explorer. "The DOJ emphasized the goal of the settlement was to ensure a competitive environment for so-called middleware applications, such as Web browsers and media players, that could help erode the Windows monopoly" (Romano 2007).
