Microsoft is canceling Claude Code licenses across its Experiences and Devices division by June 30, 2026, after six months of internal use by thousands of engineers on Windows, M365, Teams, and Surface. The memo cites cost-cutting and security integration with Azure DevOps and Defender. Engineers report frustration, with one noting 'Claude Code understands Win32 internals in a way Copilot CLI doesn't.'
