Microsoft unveiled Project Solara at Build 2026, introducing a fundamental shift in computing architecture. According to Microsoft's official announcement, the platform is designed for what the company calls 'agent-first devices', where AI agents replace traditional applications as the primary user interface. Unlike conventional operating systems, Solara operates as a chip-to-cloud platform that combines an Android Open Source Project (AOSP) base with Microsoft's enterprise stack, including identity, device management, and Copilot-powered agents. This structure allows the system to operate across both local hardware and cloud infrastructure. As reported by GeekWire, Stevie Bathiche, Microsoft corporate vice president and technical fellow who leads its Applied Sciences Group, described it as 'a bet on what the next computer looks like', noting that 'boundaries are collapsing' and traditional app models are no longer necessary. The platform represents Microsoft's first attempt to build an operating system and hardware platform around the premise that apps are being replaced by agents as the primary way people interact with computers.
The platform addresses traditional computing fragmentation by removing the need for multiple applications in complex workflows. As reported by Microsoft, agents in Solara are designed to interpret user intent and execute tasks across systems without requiring explicit app-level interaction. Instead of opening separate applications, users issue commands or prompts, and the system orchestrates workflows in the background. This shifts computing from an application model to an orchestration model, where the system determines which services to call, how data is retrieved, and how results are presented. According to GeekWire, the devices can run multiple agents at once, with a coordination layer that taps whichever agent a task requires, allowing for seamless task handoff between different AI services. The most technically ambitious element is just-in-time UI, where agents generate their own interfaces based on device form factors, eliminating the need for developers to redesign applications for each new screen size and resolution. As reported by ArsTecnica, this means the same task can produce different outputs depending on the device - a wearable may show a short summary while a larger display may show detailed controls and data.
Microsoft introduced Scout, an always-on AI agent integrated across Microsoft 365 services including Teams, Outlook, OneDrive, and SharePoint. Unlike traditional assistants that require explicit prompts, Scout operates continuously in the background, using information from emails, calendars, chats, and documents to understand user context and assist with everyday tasks. According to Microsoft, Scout can help prepare for meetings, manage scheduling conflicts, draft emails, and surface relevant information without requiring manual input. The company positions Scout as part of a new category of AI systems it calls 'autopilots', which are designed to execute tasks on behalf of users rather than simply respond to queries. Alongside Scout, Microsoft introduced seven new first-party AI models under its Microsoft AI (MAI) family, expanding its in-house capabilities across text, code, image, voice, and speech. Available through Microsoft Foundry, these include MAI Image-2.5 for image generation, MAI Transcribe-1.5 for speech-to-text, MAI Thinking-1 for reasoning tasks, MAI Voice-2 for text-to-speech, and MAI Code-1 Flash for coding applications. The company also introduced Aion models for on-device AI processing, including Aion 1.0 Instruct for Windows 11 and Aion 1.0 Plan, a 14-billion-parameter model for agent-driven workflows.
Microsoft outlined significant updates to Windows as an AI platform, positioning it beyond a desktop operating system. The company introduced support for Linux containers through Windows Subsystem for Linux (WSL), new configuration tools for development environments, and an Intelligent Terminal that integrates AI assistance directly into command-line workflows. Microsoft expanded its Windows AI APIs beyond devices with dedicated AI hardware, allowing more PCs to run AI-powered features such as speech recognition and video enhancement locally. The company outlined security features designed to support AI agent deployment, including agent containment through execution containers, identity management for AI agents, integration with Microsoft Entra and Intune, security protections through Microsoft Defender and Purview, and support for Windows 365-based agent environments. These capabilities are designed to ensure AI agents operate within defined boundaries with controlled access to files, networks, and system resources. Additionally, Microsoft announced Windows 365-based agent environments for enterprise deployment.
Microsoft has revealed the concept smart badge, a wearable device designed to replace traditional app-based smartphones with an agent-first AI interface. The device features a small touchscreen for interacting with AI agents, a top-facing camera system for environmental awareness, and a side-mounted fingerprint reader for biometric security. Additional specifications include privacy switch and volume controls, far-field high SNR microphone array and speaker, side-facing camera, and WiFi, Bluetooth, GNSS, and 5G wireless connectivity. The badge is reportedly powered by Qualcomm wearable silicon, with Microsoft stating it got the badge running on the platform in about three days using the same software as the desk device on a different chipset. The device is currently designed for frontline and information workers, replacing the traditional app-based grid interface with a streamlined, agent-centric UI. As reported by Computex 2026, the company is testing the badge and smart display devices internally among hundreds of employees, hoping to quickly move the wearable phone/computer from concept to mainstream adoption.
