Microsoft just rebuilt Copilot as a new "OS for work" today. Here's what you need to know. CEO Satya Nadella announced the biggest Copilot update yet, unifying four pieces into one app: Autopilot, Code, Home, and Office. Autopilot is a proactive, long-running agent built for the enterprise, working on tasks without constant prompting. Code lets you build apps hosted inside your own company's tenant. Home merges Chat and Cowork into one space. Office is now fully embedded in Copilot, and Copilot is embedded back into Word, Excel, PowerPoint, Outlook and Teams.
