European Union opens antitrust investigation into Microsoft's push for file format adoption

The Wall Street Journal reported that EU regulators have announced a third investigation into Microsoft's conduct on the desktop.

The investigation focuses on whether Microsoft violated antitrust laws by too-aggressively pushing for adoption of OOXML as a global standard (OOXML is the document format implemented in Microsoft Office 2007).

The new investigation follows only one month after the EU announced two other investigations, one into the integration of Microsoft's Internet Explorer Web browser into Office over competing alternatives, and another relating to the degree and ease of interoperability that Microsoft permits other vendors to achieve with Office.
