Microsoft is testing an application called "Project Odeon," which resembles the Windows 11 Settings interface and is categorized under Productivity in the Microsoft Store. The app is currently in a Preview version, identified as Microsoft.ProjectOdeon, version 1.0.9.0, and requires Windows 11 build 26100 or later with Developer Mode enabled for installation. Odeon does not replace the existing Settings app, allowing both to coexist, and it can identify system information similar to the built-in Settings app, although there are discrepancies in reported data. Some pages in Odeon appear unfinished, and it features a hidden preview mode with a dummy account for testing purposes. The architecture of Odeon suggests it may not fully replace the Settings app but could function as a modular Store app with helper executables for system-level changes. Microsoft is exploring the possibility of delivering updates to the Settings app through the Store, potentially phasing out the traditional Control Panel. There is currently no public release planned for Project Odeon.
