Microsoft is transforming Windows into an "AI operating system" that will enable AI agents to perform tasks traditionally managed by humans, such as sending emails and scheduling meetings. During the Build 2026 developer conference, Microsoft introduced 'Scout,' an AI secretary that autonomously manages tasks and integrates with a system called MSIQ for organizational workflows. CEO Satya Nadella emphasized the creation of a workspace for AI agents within Windows, supported by a security framework called "MXC" to ensure controlled operation. Each AI agent will have a unique identity for accountability. Microsoft also unveiled seven proprietary AI models, including "MAI-Thinking-1," and a semiconductor called 'Maia 200,' which outperforms Nvidia's chips. Additionally, Microsoft is developing 'Project Solara,' a prototype for dedicated devices to facilitate AI interactions.
