Microsoft has introduced a range of artificial intelligence features in Windows 11, marking a departure from Windows 10. The Calendar flyout feature, which was absent since October 2021, will return, allowing users to access it by clicking the date and time stamp in the bottom right corner of the screen. The new Copilot chatbot will integrate AI capabilities into various text boxes across the operating system, utilizing the neural processing unit (NPU) of modern PCs to enhance efficiency. The taskbar will include the "Ask Copilot" function and a new Researcher app for facilitating research. Users can opt out of these taskbar apps if desired. The "Fluid dictation" tool will convert speech to text, while Microsoft 365 applications will use AI for email summaries and automatic alt-text for images. An "Agent Mode" will enable users to create documents and spreadsheets based on simple prompts. At the Ignite 2025 conference, Microsoft emphasized its vision of Windows 11 as an "agentic" operating system capable of executing complex tasks autonomously, although this raises concerns about data security.
