At Build 2026, Microsoft’s most telling hardware announcement did not start with Windows. Project Solara is pitched as a chip-to-cloud platform for devices where AI agents, rather than conventional apps, become the primary interface.
The base layer is MDEP, Microsoft Device Ecosystem Platform, an enterprise system derived from AOSP. Microsoft has already used it in Teams Rooms hardware; Solara repurposes it for lighter edge devices that need cameras, microphones, identity, security and cloud handoff without carrying a full Windows stack.
The two reference devices made the strategy concrete: a Qualcomm-powered badge with a touch screen, fingerprint key, camera, far-field microphones, 5G and location; and a MediaTek IoT desktop unit with face sign-in, ultra-wideband presence sensing, dual microphones and USB-C ports that can become a cloud Windows endpoint when attached to a display. AccuWeather, Best Buy, CVS Health, Levi’s and Target are expected to pilot the designs in the coming months.
The important admission is that Windows is not always the best substrate for agent-first hardware. Satya Nadella framed it as a platform shift from building operating systems and devices for apps to building for agents; Steven Bathiche described the operating system as something that now spans device and cloud.
