Versions before November 2015 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 Resource Access (games) and Shared (multitasking), that feature custom virtual machines reserved for running under different environments and applications.
