Microsoft has unveiled Mu, a powerful on-device AI model built to run natively on Windows PCs inside the Settings app.Designed to understand natural language, Mu enables users to adjust system preferences using simple voice instructions.This marks a step forward in making Windows more intuitive and user-friendly.
Users can now change settings like brightness, power modes, or Wi-Fi options just by asking.Because it runs locally, Mu ensures faster responses and improved privacy.Microsoft aims to reduce clicks and confusion, bringing a smarter, more accessible control system to everyday users.

Microsoft’s Mu AI Brings Smarter, Private Assistants to Windows 11 Settings.
Microsoft has introduced a new on-device AI model called Mu, designed to power intelligent agents inside Windows 11’s Settings app.Currently rolling out on Copilot+ PCs, Mu allows users to use natural voice commands to control and manage hundreds of system settings effortlessly.From brightness to power mode, Mu interprets your spoken intent and executes the task, all without needing the cloud.Built specifically for Neural Processing Units (NPUs) in new Windows devices, Mu delivers blazing-fast responses under 500 milliseconds.
These processors, like Qualcomm’s Snapdragon X chips, handle AI tasks locally, enabling smoother, real-time performance.This local processing ensures that no personal data is sent to Microsoft servers, a big plus for privacy-conscious users.Mu is engineered to understand not only direct commands but also contextual, conversational questions.For example, users can ask, “How do I increase battery life?” or “Change screen timeout settings,” and Mu will respond with actions.
This natural interaction helps users who are less tech-savvy or want to avoid navigating deep menu layers.In its official blog post, Microsoft confirmed that Mu is central to its broader Copilot+ PC strategy, where smart local agents play a major role.Unlike traditional assistants, Mu doesn’t rely on constant online connectivity, helping reduce latency and enhancing user trust.It’s built for both speed and privacy — two key demands in the modern AI era.
As Windows 11 continues evolving, Mu sets a strong foundation for future AI-native tools within the OS.With privacy-first design and cutting-edge voice understanding, Mu could redefine how millions interact with their PCs daily.
