By 2004, the project had become a bloated, unstable mess due to feature creep and spaghetti code built on top of the aging Windows XP codebase. Microsoft famously "reset" the project in 2004, scrapping much of the original Longhorn code, ultimately resulting in the release of Windows Vista in late 2006. The original Longhorn was lost to time—never officially released. windows longhorn simulator
Because the simulator is rendering fake acrylic blur, shadow overlays, and polling for tile updates, it can consume 10-15% CPU on a modern i5. On a laptop, it drains battery faster than real Windows 11.

Longhorn simulators focus on a period between 2001 and 2004, capturing the "Frutiger Aero" aesthetic and experimental features that were largely scrapped or significantly "neutered" when the project became Windows Vista.
