Microsoft has introduced an AI assistant named Mu for Windows 11’s Settings, allowing users to ask questions in natural language through the search bar. Users can issue commands like “turn on dark mode” or “disable notifications for Teams,” and Mu will either navigate to the settings or execute the changes. Mu has 330 million parameters and is trained on 3.6 million examples, processing requests in under 500 milliseconds. It operates on a device’s Neural Processing Unit (NPU), requiring a Copilot+ PC for full functionality, and handles data locally, enhancing privacy and security.
