On March 17, 2026, Microsoft discreetly rolled out an update for the PC iteration of the Xbox app, unveiling a novel functionality that empowers users to personally incorporate third-party games and applications installed on their local systems. Users can navigate to the game library interface, tap on the '+' symbol situated in the upper-right corner, and proceed to include any .exe program, tailoring its name, icon, and launch settings to their preference. This innovative feature takes cues from Steam's 'adding non-Steam games' functionality, with the objective of solidifying the Xbox app's stance as a central hub for PC gaming. The update aligns the Xbox app's capabilities more closely with Steam's Big Picture Mode, providing further evidence of Microsoft's commitment to propelling forward its Xbox PC strategy.
