[JURIST] The European Union [official website] has given software giant Microsoft until the end of May to comply with its antitrust order [Microsoft's implementation plan for the agreement] or face punitive sanctions, officials for both organizations said Monday. The dispute is due mostly to what regulators see as Microsoft's lack of cooperation in providing server software source codes to competitors and whether the Windows package they were forced to produce is up to standard. The EU has the power to fine Microsoft up to five percent of it daily sales globally but Microsoft said it continues to work with the EU towards a goal of full compliance. AP has more.
