Overview
- The leaked demo video was posted publicly on July 2, 2026 after circulating on BetaWiki and Discord and was republished by a Microsoft watcher.
- The prototype, codenamed Aion, runs on a slimmed-down Windows codebase called Win3 and a modified Edge shell that favors web apps instead of traditional Win32 desktop applications.
- Aion’s interface places Copilot at the center with a multi‑modal Omnibox, goal‑grouping called Spaces, AI‑generated task windows and interactive plugins that surface controls inside chat.
- The demo shows context routing to enterprise or consumer Copilot and a forward‑slash trigger for Context IQ tied to Microsoft 365, plus seamless handoff to Windows 365 Cloud PC for legacy apps.
- Reporters and unnamed sources say the footage is likely from 2024 and experimental, Microsoft has not confirmed plans to ship Aion, and elements may instead inform current Windows work while raising enterprise and privacy trade‑offs.
