The EU never sanctionned Microsoft for monopoly. They received $2bn fines in 2005 for lack of transparency on the documentation for drivers, if I remember, then a little extra for paperwork. Then Microsoft complied mostly at the last minute before being fined (even for the 6-months disappearance of the Browser Choice Dialog, it only cost them $500m).
But never, never has the EU sanctionned Microsoft for signing OEM deals that prevent companies from installing other OS than Windows.
