This update integrates artificial intelligence deeply into the operating system, transforming Windows 11 machines into 'AI PCs' with hands-free interaction capabilities through the intelligent assistant, Copilot. Key features include "Hey Copilot" voice activation, Copilot Vision for analyzing on-screen content, and Copilot Actions for performing multi-step tasks autonomously. These advancements are available to all Windows 11 PCs, democratizing access to AI technology. The update is expected to drive a migration from Windows 10 and reshape the competitive landscape for AI and computing. Microsoft aims to make AI a fundamental part of the user experience, setting new standards for interaction and potentially impacting various device categories. Future developments will focus on enhancing AI capabilities and ensuring privacy and security measures are in place.
