Less than one year after being fined 899 million Euro for failing to comply with the decisions of an antitrust case, Microsoft is once more targeted by the European Commission which accused the Redmond-based company of being harmful towards competition in the browser market through its decision of bundling Internet Explorer with its Windows operating system. According to the EC, Microsoft's has used its dominant position in the OS market to also gain control over most of the browser world although, one must note, IE has been doing worse these last few years as Mozilla's Firefox gained popularity. In December 2007 Opera Software, the developer of the Opera browser filed a complaint against Microsoft with the European Commission in which it militated for consumer choice and the support of open Web standards in Internet Explorer.

Given eight weeks to reply to the accusations, Microsoft may again find itself fined if the EC finds it guilty, and will be forced to take measures in order to respect EU competition laws. Microsoft went on to state that it intends to be in "full compliance with European law."
