# UK Regulator Proposes Strategic Market Status for Microsoft Business Software CMA investigates Microsoft's market dominance and potential anti-competitive bundling practices in business software. - **Source:** [www.theregister.com - Articles](https://brifing.si/source/2c34ea50-d341-4a10-925d-12c012a9ad10) - **Published:** 2026-10-16 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/6e096d8c-b5f9-4cd4-8438-4e4eae2f99b9 ## Regulatory Intervention Strategy The UK Competition and Markets Authority is proposing to designate Microsoft with Strategic Market Status regarding its business software portfolio. This regulatory move aims to address concerns over entrenched market power across five key areas, including operating systems and productivity suites. The watchdog seeks to ensure a level playing field for competing software developers. ## Scope of the Investigation The probe covers Microsoft’s integrated software stack, specifically Word, Excel, Outlook, PowerPoint, and Teams. Regulators are also scrutinizing security, server, and database management systems. The investigation, initiated in May, evaluates whether this unified environment creates barriers that prevent customers from switching to alternative providers or adopting superior third-party software solutions. ## Bundling and Cost Barriers The CMA highlights that Microsoft’s discounted pricing for bundled applications discourages customers from adopting rival products. Because organizations often view the portfolio as a unified environment, switching providers would result in duplicate licensing costs. This financial structure effectively locks businesses into the Microsoft ecosystem, limiting their ability to choose best-in-class tools. ## Potential Regulatory Remedies Proposed interventions include mandates to ensure technical design choices do not restrict interoperability with other providers. The regulator may also restrict specific commercial arrangements, such as bundling, to prevent Microsoft from leveraging its market power to distort competition in adjacent sectors like cloud services. These measures aim to restore genuine market choice. ## Cloud and AI Scrutiny The investigation extends to whether Microsoft’s licensing terms increase costs for deploying Windows Server on non-Microsoft clouds. Furthermore, the CMA is examining if customers can freely choose AI tools or if Microsoft’s Copilot unfairly dominates the landscape. The regulator continues to monitor barriers to multi-cloud deployments alongside AWS and Microsoft. ## Microsoft’s Official Response Microsoft maintains that its products remain open and interoperable, allowing customers to integrate competing services seamlessly. A company spokesperson stated they do not share the CMA’s views, emphasizing that their solutions provide attractive pricing and flexibility. Microsoft intends to engage constructively with the regulator to demonstrate the benefits of their current competitive model. ## Industry Stakeholder Perspectives The Browser Choice Alliance and the Open Cloud Coalition have expressed strong support for the CMA’s proposal. These groups argue that Microsoft’s restrictive licensing practices distort competition and increase costs for businesses. They view this regulatory action as a significant opportunity to dismantle long-standing barriers that have hindered alternative software providers for decades. ## Timeline and Future Outlook The CMA has opened a consultation period for the proposed decision, with comments due by November 13. A final determination is scheduled for February 13, 2027. This case is being closely monitored by international bodies, including the US Federal Trade Commission and the European Commission, as they consider similar regulatory actions globally. ## Sources covering this story - https://www.theregister.com/software/2026/10/16/british-watchdog-seeks-tougher-terms-around-microsofts-dominance-of-business-software/5303520 — --- _Summary written by Brifing from the original reporting.
