UK Regulator Opens Antitrust Probe Into Microsoft's Business Software
The UK's Competition and Markets Authority (CMA) has opened an investigation into whether Microsoft's bundling of products like Windows, Word, Excel, Teams, and Copilot may hurt competition. The CMA said that Microsoft's cloud licensing and product integrations might limit customer choice and make it hard for other tools to work with Microsoft's software. The investigation will look at both technical and contract issues, including how embedding Copilot may give Microsoft an early advantage in AI tools. The case may lead to new rules for Microsoft, but the outcomes could focus on changing behaviors rather than breaking up the company. The fact-finding will continue into late 2026, with decisions expected by early 2027.
