In July 2026, a video, purportedly an internal Microsoft leak, surfaced, offering a glimpse into an experimental operating system internally codenamed Project Aion. Constructed atop the Edge browser and leveraging a streamlined Windows Web3 codebase, this innovative system places Copilot at its core, facilitating seamless, full-scale AI interaction. It does so by eschewing the conventional desktop and Start menu in favor of a more intuitive, AI-centric interface. Users can effortlessly summon Copilot through a dedicated taskbar located at the bottom of the screen, which supports three primary AI service modules. Additionally, the system introduces a novel Spaces feature, designed to intelligently categorize and group applications and web pages, enhancing user organization and efficiency.

It's important to note that this system is exclusively tailored for web applications and websites, rendering it incompatible with traditional Win32 programs. However, users seeking desktop functionality can seamlessly access it through Windows 365 cloud services, ensuring a versatile and adaptable computing experience.
