Microsoft rebuilds Windows for agentic AI: MXC sandbox, hybrid intelligence, new Search

Microsoft outlined its plan to prepare Windows for agentic AI: the Microsoft Execution Containers sandbox to isolate AI agents, a "hybrid intelligence" approach combining local and cloud models, new Copilot modes (Home, Code, Autopilot) and a Search that performs actions directly from the taskbar. Support for Nvidia RTX Spark and ARM gaming is also being expanded, with Call of Duty coming to RTX Spark in 2027.

• MXC sandbox restricts AI agents' access to files and networks
• Hybrid intelligence combines local and cloud models to cut token costs
• Copilot gains Home, Code and Autopilot modes on Copilot+ PCs in coming months
• Call of Duty arrives on RTX Spark in 2027, ARM gaming support expands
