The European Commission may take weeks to decide whether to fine Microsoft for non-compliance with its 2004 anti-trust judgement, according to reports.
The company has just finished arguing its case in Brussels, in a private hearing that was completed by the weekend.
Microsoft claims it is in compliance with EC legislation, but the European Commission has so far stuck to its guns and continued to threaten a daily £1.4m fine for non-compliance.
Microsoft was also rapped over the knuckles by the Commission last week for planning a press conference on Thursday, after the first day of the hearing.
The Commission said the hearing was private and that Microsoft could not hold the conference – prompting Microsoft to back down and cancel the conference.
The Commission wants Microsoft to produce user-friendly documentation of its workgroup server protocols to allow its rivals to more easily produce rival products that can work in a Windows environment.
Microsoft says it already has done so, but the Commission says that the documentation so far produced is not adequate for the purposes of rival suppliers.
