Microsoft is integrating artificial intelligence into Windows 11 with significant updates, including a new AI agent named Copilot Actions designed to assist users and enhance productivity. The update features a "Hey Copilot" wake word for activating Copilot Vision mode, allowing for a hands-free experience. A semantic farewell phrase will enable users to conclude voice sessions seamlessly. The Copilot Vision feature is currently in preview and is expected to roll out more broadly next month. However, a retracted advertisement revealed challenges with Copilot's performance, indicating the need for further refinement of the AI's capabilities.
