Microsoft Hit with UK Competition Regulator Probe over Software Business
The probe could let the regulator impose conduct rules as it weighs whether Microsoft’s licensing limits competition for hundreds of thousands of UK users.
- On Tuesday, the UK Competition and Markets Authority announced a Strategic Market Status investigation into Microsoft's business software ecosystem, commencing in May to address licensing concerns.
- A July 2025 inquiry found Microsoft and Amazon each held up to 40% of UK cloud spend, with licensing practices identified as harming competition. Both firms recently took steps to reduce egress fees, yet the CMA says further action remains necessary.
- The investigation spans Windows, Word, Excel, Teams, and Copilot, used by hundreds of thousands of UK businesses and public sector organizations. The probe could take up to nine months, potentially enabling the CMA to impose conduct requirements.
- Nicky Stewart, senior advisor to the Open Cloud Coalition, welcomed the probe and urged "swift action" if Microsoft and Amazon fail to meet commitments. Some industry observers raised concerns that excluding Amazon from this investigation could create regulatory imbalance.
- CMA CEO Sarah Cardell stated the designation would "ensure a level playing field as AI is rapidly embedded into everyday business software tools." Parallel investigations in Brazil and Japan signal growing international scrutiny of Microsoft's corporate software practices.
