Microsoft has unveiled a Windows strategy built around “hybrid intelligence,” combining local and cloud AI so agents can run each task where it belongs while staying under user and IT control. The push spans Windows 11, Copilot+ PCs, developer tools and computers for local AI workloads.

We’re supercharging Copilot on Windows with Hybrid Intelligence.

Microsoft Execution Containers are now generally available on Windows 11. MXC lets organizations define which files and networks an agent may access, with policies enforced at runtime. It pairs containment with agent identity and management through Agent 365 and Intune, allowing IT to separate an agent’s actions from those of the device user. Codex, GitHub Copilot and OpenClaw already support MXC. Claude Code, Perplexity and Raycast are due to follow, while Meta’s Muse for Windows is coming as a native app with MXC integration.

Microsoft is also moving larger models onto PCs. MAI Code 1.1 Flash uses 3-bit precision to cut its size by nearly 80% while retaining a 256K local context window. Windows ML is gaining llama.cpp support across GPU, NPU and CPU. GitHub HydraFusion will route work between cloud and on-device models in experimental previews for the GitHub Copilot app, GitHub Copilot CLI and Visual Studio Code later in October.

With permission, Copilot will use this hybrid layer on Copilot+ PCs to draw on local files and recent activity, perform Windows actions and call models running on the device. The capabilities are expected to begin rolling out in the coming months across Copilot Home, Code and Autopilot.

The hardware plan ranges from always-on mini PCs to RTX Spark builder machines and DGX Station systems. Surface Laptop Ultra, with up to 128 GB of unified memory and support for models above 120 billion parameters, is available for pre-order and arrives October 16. DGX Station for Windows systems supporting models up to one trillion parameters are due later this year. Windows Search actions will also let Insiders toggle settings, manage windows and send messages from the taskbar. Microsoft is tying Windows, Copilot, GitHub, Surface and NVIDIA hardware into one platform for secure agents and local AI, from personal PCs to shared enterprise compute.
