Leaked materials from 2024 have revealed that Microsoft has built a working prototype Copilot OS that is platform agnostic, derived from the Microsoft Edge web browser and runs on top of Windows or Android, focused on the web and agentic experiences.
This project is codenamed Aion, and while its status is currently unknown, the leaked materials confirm that such a project was in active development and reached a stage in which the code was functional. With all the material leaked, we have a pretty good idea about how this OS experience looked and functioned.
