The European Commission outlined for the first time today remedies it intends to impose on Microsoft for what it called continuing abuses of its dominant market position.
The EU executive said it was giving Microsoft a final chance to comment before it orders the global leader to share crucial interface information with competitors in the server market and requires it to allow fairer competition for media players.
"The Commission's preliminary conclusion is that Microsoft's abuses are still ongoing," it said in a statement.
It said Microsoft was leveraging its dominant position from PCs into low-end servers, which provide core services to PCs in corporate networks.
On media players, used to play sound and movies on computers, the Commission said Microsoft had two alternatives.
It could either untie Windows Media Player from its ubiquitous Windows operating system by being required to offer a version of Windows without Media Player, or it could agree to include competing media players with Windows.
"Both solutions seek to ensure that consumers have a fair choice as regards media players," the Commission said.
