Microsoft pulls Claude Code licenses, pushes engineers to Copilot CLI

Microsoft is winding down internal access to Anthropic’s Claude Code by the end of June, redirecting thousands of developers to its own GitHub Copilot CLI. The Experiences + Devices group — covering Windows, Microsoft 365, Outlook, Teams, and Surface — will lead the transition. Executive Rajesh Jha framed the move as consolidation around a tool Microsoft can shape directly with GitHub, but the June 30 cutoff aligns with the end of Microsoft’s fiscal year, making license cancellation a convenient operating-expense trim.

The shift comes despite Claude Code proving more popular than Copilot CLI among Microsoft’s own engineers since the December rollout. That preference cannibalized adoption of GitHub’s competing product and dented Microsoft’s previously cited 91 percent Copilot usage figure across engineering teams. Microsoft had even broadened access to non-engineers like designers and PMs, who used Claude Code to prototype without prior coding experience — a workflow now disrupted.

The Anthropic relationship stays intact at the platform layer: Claude models remain available through Copilot CLI, Microsoft Foundry, and Microsoft 365 Copilot, where they outperform OpenAI counterparts on certain tasks. Microsoft remains one of Anthropic’s largest customers and reportedly counts Claude sales toward Azure quotas. The pressure now falls on the GitHub team to close the capability gap that drove engineers to Claude Code in the first place.
