A leaked video has surfaced showing what appears to be “Copilot OS” — a stripped-down, lightweight version of Windows built entirely around Microsoft Copilot and agentic AI. The footage, reported by Windows Central and shared via BetaWiki Discord, reveals a concept Microsoft reportedly developed in 2024 under the codename “Aion.”
What Is Copilot OS?
Unlike traditional Windows, Copilot OS is a Chrome OS-like experience centered on the Edge browser and web applications. The desktop UI is minimal, with Copilot acting as the primary interface layer. Instead of the classic Start menu and taskbar, users interact through an AI-driven shell that anticipates tasks, manages workflows, and runs agentic processes autonomously.
Key features visible in the leaked video:
- AI-First Desktop: The entire UI is built around Copilot, with the AI assistant occupying center stage rather than being a sidebar tool.
- Agentic Workflows: The OS can spawn autonomous AI agents to handle tasks like file management, scheduling, and data analysis.
Web-Centric: Built heavily around Microsoft Edge and Progressive Web Apps (PWAs), similar to Chrome OS.
Not to Be Confused with Project Solara
Interestingly, Microsoft also showcased Project Solara at Build 2026 — a separate Android-based OS for AI agent gadgets like desk assistants and wearable badges. While Solara targets dedicated AI hardware, Copilot OS appears to be a Windows exploration aimed at traditional PC form factors.
A Windows Central report confirms that sources have verified the leaked video as authentic internal Microsoft material from 2024. However, there’s no indication whether Copilot OS will ever ship as a commercial product or if it remains an internal experiment.
Why This Matters for PC Users
For PC enthusiasts and everyday users, Copilot OS signals where Microsoft sees the future of computing heading:
1. AI as the operating system, not just an add-on
2. Web-first computing becoming the default paradigm
3. Lower hardware requirements for basic computing tasks
4. Automation of routine tasks through AI agents
If Microsoft ever ships Copilot OS, it could challenge Chrome OS in education and budget segments while offering a radically different Windows experience for mainstream users.
FAQ
Will Copilot OS replace Windows 11/12?
No — Copilot OS appears to be an experimental concept, not a Windows replacement. It’s more likely to coexist as a lightweight SKU or influence future Windows features.
When will Copilot OS be released?
Microsoft hasn’t announced any release plans. The leaked video is from 2024, and the company hasn’t confirmed whether this will become a commercial product.
Can I try Copilot OS now?
No public build is available. The leaked video is the only glimpse we have so far.
How is this different from Microsoft’s other AI projects?
Project Solara runs on Android for dedicated AI gadgets, while Copilot OS is a Windows exploration for traditional computers. Think of Solara as AI hardware and Copilot OS as AI-native Windows.

Final Verdict: Copilot OS is one of the most intriguing Windows concepts we’ve seen in years. While it may never ship, it reveals Microsoft’s vision for an AI-first computing future — and that alone is worth paying attention to.
