Windows ML, DirectML's successor, is built on the open ONNX format rather than DirectX, so it runs across GPUs, NPUs, and CPUs from any vendor, adding hardware support via downloadable Execution Providers instead of driver updates that took six months to adopt.

Why it matters
Windows is building native agent-identity support and a centralized local MCP server registry directly into the OS, worth tracking for anyone choosing where to run agentic dev workflows.
