Microsoft declined to comment on the project. The leaked material does not establish Project Aion as a product Microsoft plans to release.\n\n## Project Aion Replaced the Windows Shell With Copilot\n\nIn the Win3 demonstration, Project Aion ran without the familiar Windows Start menu, desktop icons, or pinned taskbar apps. Copilot acted as the main launcher. The shell worked through Edge and used web technology for apps, websites, and system tasks.\n\nClicking the Copilot button opened a dashboard that greeted the demo user with \"Good afternoon, Nathan.\" Three cards appeared for Stay on Top, Create something new, and News of the day. A My Stuff row showed Edge, Teams, Outlook, OneDrive, and Microsoft 365, along with Figma and Visual Studio Code.\n\nThe internal material described Aion as an \"Agent/Copilot OS\" meant to run on AI-focused devices using AOSP, Win3, or Windows 11. AOSP is the open-source base for Android. Another internal description called Aion \"a portable, web-shell\" built with a modified Edge and linked to Windows 365 for full Windows desktop access.\n\nThe cross-platform approach allowed Aion to run as a replacement shell on Windows 11 or on AOSP Android. Win3 was a separate, lighter Windows codebase designed for faster startup, longer battery life, and improved security, but it did not support legacy applications.\n\nAion's \"Ask me anything\" field was the main way to open apps, browse the web, and start tasks. Typing \"techc\" suggested TechCrunch, while entering \"to do\" brought up Microsoft To Do in a floating Edge picture-in-picture window instead of opening a native Windows app.\n\nMore complex requests changed the interface. Asking for dining options in Maui opened a floating Copilot chat with restaurant names and travel links. A separate question about meetings for the next Monday opened another chat window next to it.\n\nEach conversation got a taskbar icon based on its topic, rather than another Copilot symbol. The Maui dining chat used a martini-glass icon, the meeting chat used a calendar icon, and closing a chat saved it as a chip under My Stuff so the task could be reopened later.\n\n## Project Aion's Spaces, Microsoft 365 Integration, and Desktop App Limits\n\nA feature called Spaces grouped apps, websites, files, and conversations by goal. One example, TURKEY TRIP, included a Description and Goals card for planning a trip to Turkey in September, a Personal topic setting, a creative conversation style, and entries for Edge, [WhatsApp](https://www.ghacks.net/2026/08/26/whatsapp-adds-multiple-passkeys-alphanumeric-passwords-and-caller-context-in-security-update/), [YouTube](https://www.ghacks.net/2026/08/22/youtube-reportedly-offering-creators-millions-to-keep-content-exclusive-and-off-netflix/), Word, Turkish Airlines, Expedia, and [Airbnb](https://www.ghacks.net/2026/02/16/airbnb-tests-ai-powered-natural-language-search-for-rental-bookings/). The Turkey Space also had a Draft an itinerary action, and its Contents area split material into Recents and Suggested tabs.\n\nThe work-focused portions of Aion connected directly to Microsoft 365 information. In one demonstration, a request about Scott Schenone led Copilot to search SharePoint and email, identify him as a Senior Design Director working on the Lanai project, and summarize his recent work from internal documents.\n\nTyping a forward slash into the search field triggered Context IQ, which surfaced coworkers and files from Microsoft 365 to place directly into a prompt. Copilot could also draft an email inside an Outlook-style compose window with tone controls labeled Casual, Professional, Funny, and Undead Pirate Captain, then send the message without opening Outlook.\n\nEdge also let Aion access the underlying HTML of websites using a process Microsoft called DOM crawling. The leaked material described this as reading the page structure to understand content beyond what is visible on the screen.\n\nThe Win3 version in the leak could not run traditional Win32 desktop programs natively. If a task needed a full desktop app, Aion would send the user to Microsoft's Windows 365 Cloud PC service, streaming a Windows session with the document already open and a Copilot Summary panel available.\n\nThis restriction showed up in an Excel demo with a table comparing square footage across property listings. Aion replied, \"I'm sorry, I cannot open Excel for you,\" then built the comparison inside the chat, gave a working download button, pointed the user to the Excel progressive web app, and showed a \"Suggested tools: Excel\" chip.\n\nThe design went beyond a standard desktop layout. One leaked sheet showed three setups: Landscape with Docked Conversation, Portrait with Docked Conversation, and Soft Keyboard. A Maui dive-shop research task adapted to a tablet-style portrait view with an on-screen keyboard. Aion's address field also worked as an omnibox. Typing \"maui\" brought up location-aware suggestions and filters for Microsoft, History, Favorites, and Tabs.\n\n## How Project Aion Connects to Microsoft's Public Windows AI Plans\n\nMicrosoft's public Windows work has continued with Windows 11. In November 2025, the company started testing AI agents on the Windows 11 taskbar through Ask Copilot.\n\nThis included showing task progress on the taskbar and giving access to agents like Researcher in Microsoft 365 Copilot. These agent tasks use Microsoft's separate Agent Workspace for Copilot Actions, which runs apart from the user's main Windows session.\n\nMicrosoft has also kept working on standard Windows interface parts, such as a customizable Windows 11 context menu and moving core Windows features to WinUI 3. The company has also worked on performance for File Explorer, the Start menu, and other areas of Windows 11.\n\nOn March 20, 2026, Microsoft said in a Windows quality update that it was cutting unnecessary Copilot entry points, starting with Snipping Tool, Photos, Widgets, and Notepad. The current focus is on performance, reliability, interface quality, personalization, and more selective use of AI features.\n\nThe leaked material does not show that Project Aion is a product Microsoft plans to release. The prototype came from a 2024 incubation effort, reached working code, and was experimental.\n\nIts current status is unknown, and Microsoft declined to comment after the leak. It is not confirmed whether any Aion ideas will reach a shipping product or how they might connect to Microsoft's ongoing Windows 11 and Copilot work.", "url": "https://wpnews.pro/news/microsoft-os-prototype-project-aion-leaked-revealing-copilot-centered-interface", "canonical_source": "https://www.ghacks.net/2026/08/27/microsoft-os-prototype-project-aion-leaked-revealing-copilot-centered-interface/", "published_at": "2026-08-27 19:12:49+00:00", "updated_at": "2026-08-27 19:19:22.362008+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products", "ai-agents"], "entities": ["Microsoft", "Copilot", "Microsoft Edge", "Windows", "Win3", "Windows 11", "AOSP", "Microsoft 365"], "alternates": {"html": "https://wpnews.pro/news/microsoft-os-prototype-project-aion-leaked-revealing-copilot-centered-interface", "markdown": "https://wpnews.pro/news/microsoft-os-prototype-project-aion-leaked-revealing-copilot-centered-interface.md", "text": "https://wpnews.pro/news/microsoft-os-prototype-project-aion-leaked-revealing-copilot-centered-interface.txt", "jsonld": "https://wpnews.pro/news/microsoft-os-prototype-project-aion-leaked-revealing-copilot-centered-interface.jsonld"}}
