A decision, to come from CFI president, Bo Vesterdorf, is not expected to be reached for around two months. It is within Vesterdorf's purview to suspend just one of the remedies, or both, or to fully deny the request.After a five-year investigation, the\u00a0Commission ruled in March\u00a0that Microsoft had abused its dominance in the PC operating systems market to gain an edge in related markets, such as media players, giving it an unfair advantage over rivals like RealNetworks Inc. It ordered the company to pay a fine of \u20ac497 million, or around $600 million, and offer a version of its Windows operating system in Europe without its Windows Media Player (WMP) software. It also ordered Microsoft to reveal enough Windows code to allow rivals to build competing server software that works with Windows.The Commission's\u00a0decision is seen as being far stiffer\u00a0than the settlement the Redmond, Wash., company reached with U.S. anti-trust authorities in that it effects the way in which Microsoft packages its products together.The company is arguing that the remedies will hamper the manner in which it offers customers new features, and that significant competition already exists in the market.Although Microsoft is putting all of its legal firepower behind appealing the decision, it said earlier this week that it has already "spent millions" to be able to comply with the Commission's demands to change Windows, should it lose its appeal.The request for a suspension of the remedies is just the beginning of an appeal process that legal experts have estimated could take anywhere from two to five years.Microsoft's arguments at the CFI Thursday morning were due to be followed by those of intervening parties in support of the software maker, such as the Computing Technology Industry Association.Commission representatives and intervening parties supporting its case were slated to speak in the afternoon.
