The Wall Street Journal and Information Week reported this morning that EU regulators have announced a third investigation into Microsoft's conduct on the desktop. This latest action demonstrates that while the EU has settled the case against Microsoft that ran for almost a decade, it remains as suspicious as ever regarding the software vendor's conduct, notwithstanding Microsoft's less combative stance in recent years. The news can be found in a story reported by Charles Forelle bylined in Brussells this morning. According to the Journal, the investigation will focus on whether Microsoft 'violated antitrust laws during a struggle last year to ratify its Office software file format as an international standard.' The article also says that the regulators are 'stepping up scrutiny of the issue.'
