Watch: Leak from 2024 shows off Microsoft's Copilot OS for PCs, and it's nothing like Windows 11

Watch: Leak from 2024 shows off Microsoft's Copilot OS for PCs, and it's nothing like Windows 11 describes a leaked, reportedly 2024 Microsoft concept for a Copilot-first PC operating system. The project, codenamed “Aion,” is presented as web-based and running on a modified version of Microsoft Edge, rather than functioning like the traditional Windows desktop. A leaked video discussed via BetaWiki and later reposted by a Microsoft watcher reportedly shows a redesigned interface that replaces the Start menu with an AI model called “Sydney,” tied to Copilot. The concept includes an “Omnibox” that routes queries to enterprise or consumer Copilot, depending on the prompt. A forward slash (/) is said to trigger “Context IQ,” which pulls data from Microsoft 365 for targeted prompts. The article also says “Spaces” group items by goals instead of app or tab categories, powered by an engine named Silverstone. Because it runs on Edge, it cannot support legacy Win32 desktop apps, but it includes a “handoff” that remotes into a Cloud PC. The leak further mentions interactive plugins and on-screen controls, such as an email summary interface.
