The UK’s competition regulator, the Competition and Markets Authority (CMA), opens an antitrust probe into Microsoft’s practices related to its business software. The investigation focuses on questions about whether Microsoft’s approach could restrict competition or strengthen dominance in the market for business software. The CMA examines how Microsoft’s products and business arrangements may affect rivals and customers, including whether Microsoft’s conduct harms competition through its software ecosystem. The probe forms part of the CMA’s mandate to assess suspected breaches of UK competition law and to determine whether Microsoft’s business practices warrant further enforcement action. The outlets report that the CMA’s investigation is an enquiry into Microsoft’s business software dominance, rather than a court ruling, and it follows the regulator’s assessment of the issues it is raising. No final findings are reported at this stage, and the investigation proceeds according to the CMA’s process.
