According to Satya Nadella on Twitter, Microsoft is transforming how users interact with Windows PCs through Copilot, an AI assistant that enables natural language communication, visual understanding, and autonomous task execution. This innovation leverages advanced AI models to let users talk to their PCs as they would to a person, while Copilot can interpret on-screen content and take actions on behalf of the user. The development signals a major shift toward multimodal AI interfaces, which are expected to boost productivity and create new business opportunities in sectors such as enterprise automation, accessibility solutions, and personal productivity tools (Source: @satyanadella, Twitter, Oct 16, 2025).
