At Build 2026, Microsoft unveiled its vision for the future of computing in the era of AI: A platform that exists liminally between devices and the cloud, capable of agentic capabilities and being always available to assist you in the flow of work.

This vision is codenamed Project Solara, but it’s more than just a vision. Microsoft is already working towards this future, building out a new, lightweight and secure OS on top of AOSP, not Windows, that it calls the Microsoft Device Ecosystem Platform (MDEP.)
