- Aion's 'Ask me anything' field serves as the main entry point for opening apps, browsing the web, and starting tasks.
- Spaces in Aion groups apps, websites, files, and conversations around a specific goal.
- The leaked material does not confirm Project Aion as a product that Microsoft plans to release, and the company declined to comment.
- The broader concept of Copilot OS is described as an operating system designed around an agent that organizes the capabilities of computers and clouds on behalf of users.
- Copilot is envisioned as the primary means for users to express themselves, consume entertainment, learn, and complete tasks in their daily lives.

Leaked documents from Microsoft reveal Project Aion, an experimental operating system concept that positions Copilot OS at its core. This AI-centric platform aims to serve as an agent of agents, organizing user tasks and interactions across devices.123789
The project is described as a self-driving OS, indicating a push towards an autonomous system that enhances user experience. The leaked SharePoint material outlines a vision where Copilot becomes the primary interface for expression, entertainment, and task completion, operating without traditional elements like the Windows Start menu.4
According to the documents, Copilot would facilitate interactions through an "Ask me anything" feature, allowing users to open apps and browse the web seamlessly. The system is designed to connect directly with Microsoft 365, enhancing productivity by grouping relevant apps and information around specific goals.

Despite the ambitious vision, the future of Project Aion remains uncertain. Microsoft has not confirmed any plans to release this OS, and there are indications that the company is strategically downplaying AI features for the time being. As noted, “Microsoft is still busy working on those agents,” suggesting that while the timeline for a fully AI-driven desktop may be extended, the pursuit of an AI-centric operating system is ongoing.
The leaked material emphasizes the importance Microsoft places on AI for its future, indicating that the concept of Copilot OS is far from dead, even if its immediate prospects are unclear.
“The leaked SharePoint material describes Copilot as an 'agent of agents' that marshals all device and cloud capabilities, with tabs like 'Self Driving OS' and 'Key Tech'. The prototype, from a 2024 incubation effort, reached functional code but its current status remains unknown, and Microsoft declined to comment.”
