Microsoft CEO Satya Nadella is positioning Copilot as a "new OS for work" spanning every model, form factor, and task, announcing its biggest update yet: an enterprise Autopilot for proactive long-running agents, Copilot Code for building apps inside company tenants, a unified Home (Chat + Cowork), and full Office embedding. Copilot is also invokable in Teams, with a new "Today" experience proactively surfacing key M365 information. Analyst Caroline Milanesi notes the separate-layer strategy (agents, apps, Office inside) lets Microsoft compete on the workflow itself without dragging along Windows legacy.
