The European Commission has fined Microsoft for 899 million euros last night after Microsoft failed to comply with its 2004 anti-trust lawsuit.

This fine adds to the 499 million euros that it has to pay to the European Commission, after finding it was abusing its dominance.

The new penalty is a sum of daily fines between June 21, 2006 and October 21, 2007 - after it was found that it was putting rivals unreasonable prices to get access to Microsoft’s source code.
