Xbox One OS

Xbox One OS (codenamed Durango) is a MinWin-derived firmware developed by Microsoft to run on the Xbox One and Xbox Series X/S consoles, which was released with the original Xbox One console on 22 November 2013. Versions before 2014 are based on the Windows 8 codebase, whereas later versions are based on the Windows 10 and Windows 11 codebases.

It includes a host OS that contains a heavily-modified version of the Hyper-V hypervisor. It also includes two partitions, namely Exclusive (games) and Shared (multitasking), that feature custom virtual machines that are reserved for running under different environments and applications.
