After it paid a striking $1.35 billion fine to E.U., the largest in its history, Microsoft has again to deal with the European lawmakers.

While the last year’s accusation of the European Commission regarded the overwhelming fees requested by Microsoft in order to deliver developers the source code of Windows, this time the Directorate General for Competition of the commission charged the Redmond giant for distributing its own web browser along with the operating system since 1996.

Ironically, Microsoft had to deal with a similar situation in 2002, when the U.S. court accused the company for breaking the antitrust laws by bundling Internet Explorer to Windows.

Addressing this situation, the European lawmakers insisted that the fact that the case has been turned down in the United States does not mean that the European Commission will not take all the necessary measures to analyze the same situation.

If the commission concludes that Microsoft has broken the European antitrust laws, the company will have to give out of its pocket a presumably large amount of money, adding to the previous $2.5 billion in fines.

As with the prior situations, Microsoft issued an official statement in which the company reiterates that all its activity is complying with the laws in the European Union. According to the European lawmakers, Microsoft has two months to send an official reply to the commission, along with a request for further examination of the case.
