Other antitrust regulars have cited IE's dominance as well. In October 2007, for instance, a group of U.S. state attorneys general urged a federal judge to hold Microsoft to a 2002 antitrust settlement another five years, in part over concerns over IE. A year ago, U.S. District Court Judge Colleen Kollar-Kotelly extended her monitoring of Microsoft to November of this year.
Microsoft has eight weeks to respond to the Commission's charges, and can request a hearing to defend itself, which it has done several times in its history with the EU.
On Friday, Microsoft's only comment was that it is "committed to conducting our business in full compliance with European law," and that it is studying the charges before deciding whether and how it would reply.
