The European Commission has cautiously acknowledged the announcement by Microsoft that it intends to commit to a number of principles to promote interoperability in markets where it holds a high market share. The Commission stated that it would consider whether these statements comply with the principles set out in the Microsoft Judgment from last year. The Commissioner for Competition also emphasised that a press release from Microsoft was not sufficient; interoperability must happen in practice. The Commission made it clear that this statement will have no bearing upon the investigations it launched in January 2008 on Microsoft’s past conduct, such as its refusal to disclose information relating to interoperability with its Office suite of products.
