Microsoft has already told EU authorities that it wants any settlement of European antitrust action to mirror the settlement in the US.
EU officials have carried out a four-year investigation into allegations that Microsoft used its domination of the operating system market to harm rivals in other markets.
One remedy being considered is the removal of Media Player, Microsoft's video software, from the Windows operating system. However, the company has said it will resist any such move.
The European Commission could fine Microsoft up to 10% of its global turnover and force it to comply with any decision it takes.
