Microsoft is preparing to walk back its recent push for Claude Code, canceling most licenses and steering developers toward its own GitHub Copilot CLI tool. The move comes after the company first opened access to Anthropic's AI coding assistant in December, inviting thousands of employees—including project managers, designers, and others without traditional coding backgrounds—to experiment with the tool on a daily basis. Since then, Claude Code has grown extremely popular inside Microsoft, but perhaps too popular for its own good.

According to internal sources, Microsoft's Experiences + Devices team—responsible for Windows, Microsoft 365, Outlook, Teams, and Surface—will phase out Claude Code by the end of June. Engineers are being encouraged to start transitioning their workflows to GitHub Copilot CLI immediately, ahead of the cutoff date. The company has framed the decision as a convergence on Copilot CLI as the primary agentic command line interface tool across the organization. However, insiders say the financial aspect is equally significant: June 30 marks the end of Microsoft's fiscal year, and canceling Claude Code licenses offers a straightforward way to reduce operating expenses as the new fiscal year begins.

In an internal memo seen by Notepad, Rajesh Jha, executive vice president of Microsoft's experiences and devices group, explained the rationale. "When we began offering both Copilot CLI and Claude Code, our goal was to learn quickly, benchmark the tools in real engineering workflows, and understand what best supported our teams. Claude Code was an important part of that learning. At the same time, Copilot CLI has given us something especially important: a product we can help shape directly with GitHub for Microsoft's repos, workflows, security expectations, and engineering needs."

The transition will not be seamless for many engineers. Microsoft had actively encouraged non-coders to use Claude Code to prototype ideas, and had originally intended for employees to run both tools side by side for comparison and feedback. In practice, many developers have favored Claude Code over Copilot CLI, highlighting gaps in functionality that now need to be urgently addressed. Microsoft had even considered acquiring Cursor to close the gap with GitHub Copilot, but has shifted its focus to different AI startups to avoid regulatory scrutiny while bolstering its AI capabilities.

The decision underscores the broader competitive dynamics in AI-assisted coding. Microsoft's relationship with Anthropic has been multifaceted—the company became one of Anthropic's top customers earlier this year, and has been counting sales of Anthropic models toward its own Azure quotas. A separate deal signed in November gives Microsoft Foundry customers access to Claude Sonnet 4.5, Claude Opus 4.1, and Claude Haiku 4.5. The cancellation of Claude Code licenses will not affect that Foundry deal, and Microsoft continues to use Anthropic's Claude models inside Microsoft 365 and Copilot for tasks where they outperform OpenAI's offerings.

Meanwhile, the pressure is now on Microsoft's GitHub team to improve Copilot CLI and try to surpass Claude Code. The company has said that 91 percent of its engineering teams were using GitHub Copilot last year, but Claude Code's popularity over the past six months has eroded that number. Microsoft now wants to reverse that trend, turning its own engineers into primary users and advocates for its own AI coding tool. "We are partnering closely with GitHub and continue to improve Copilot CLI for Microsoft engineers," Jha said. "The GitHub team has already shipped significant improvements based on Microsoft feedback, and Experiences + Devices will remain closely involved in shaping the product."

Anthropic's models will remain accessible through Copilot CLI, alongside internal-only Microsoft models and OpenAI's range. The company plans to deepen Copilot CLI's integration into Microsoft's engineering workflows, and is already encouraging developers to file bug reports and feedback before the Claude Code cutoff. The message from leadership is clear: Copilot CLI is the future, and engineers are expected to help shape it.

The decision also reflects broader trends in enterprise AI adoption. As companies rush to deploy AI coding assistants, they must balance the desire for best-in-class tools with the strategic imperative to develop proprietary ecosystems. For Microsoft, which has invested billions in AI partnerships with both OpenAI and Anthropic, the move to consolidate around Copilot CLI is a pragmatic step toward controlling its own destiny—even if it means temporarily alienating developers who have grown fond of a rival product.
