Satya Nadella declared Windows a platform for AI agents, not just human users, open-sourcing the Windows Agent Framework and launching the Windows Agent Store — a curated marketplace where developers sell agent manifests with 85% revenue share. Agents are now first-class citizens in the Windows runtime with dedicated APIs, Copilot agent mode, and native integration. This is the first time a major OS vendor has embedded autonomous agent execution and distribution directly into its platform, creating a new SaaS-alternative distribution channel.
