Windows 11 is gaining an Xbox mode that transforms a PC into a console-like experience. By installing a specific preview update (KB5083631) on Windows 11 24H2 or 25H2, users can enable Xbox full-screen mode that boots directly into a game launcher, skipping the standard Windows desktop shell. Combined with the third-party Omni Console app, this setup integrates Xbox Game Pass, Steam, and Epic Games into a single controller-friendly interface. The result uses roughly 25 fewer background processes and about 1GB less RAM than a standard Windows session, making it appealing for home theater PC setups.
