As of September 15, 2025, the Xbox app on Windows 11 no longer limits its library to Game Pass titles. A new update rolling out to all users adds an Aggregated Gaming Library that surfaces installed games from Steam, Epic Games Store, Battle.net, and GOG right alongside Microsoft’s own catalog. The update also introduces a “My Apps” section that can launch other storefronts and utilities directly, plus a cross-device play history that includes cloud-streamable games. These features, previously limited to Xbox Insiders, transform the Xbox app from a mere Game Pass storefront into a universal launcher—and they arrive just as Windows handhelds are gaining momentum.

Aggregated Gaming Library: One Place for Every Installed Game

The centerpiece of the update is the Aggregated Gaming Library. Once a supported third-party game is installed on your PC, the Xbox app automatically discovers it and adds a tile to your library under “My Library” and “Most Recent.” An origin badge—such as “Steam,” “Epic,” or “GOG”—appears on each tile so you can tell at a glance where the game resides. If you’d rather not see titles from a particular store, you can hide individual storefronts entirely from Settings > Library & Extensions.

This aggregated view does not replace other launchers; it simply acts as a discovery and launch layer. Games still install, update, and authenticate through their native clients. The Xbox app becomes the front door—handy for players who split their libraries across multiple stores and want a single list to browse.

My Apps: Launch Storefronts and Browsers from the Xbox Interface

Alongside the library changes, Microsoft has added a “My Apps” tab. This curated hub lists popular storefronts (Steam, Battle.net, EA app, etc.), web browsers, and other gaming utilities. If an app is already installed, selecting it launches it directly. If not, the Xbox app may offer a “Get” or “Install” flow; in Insider tests, this sometimes worked for storefronts like GOG Galaxy, though early builds saw occasional failures.

The goal is to reduce context switching—especially on handhelds where returning to the Windows desktop with a controller is awkward. Instead of hunting for a Steam shortcut, you can jump there from the Xbox app’s gamepad-friendly interface.

Play History Now Includes Cloud-Playable Titles

Microsoft is also upgrading the Play History feature. Later in September, the timeline will display not only locally launched games but also cloud-playable console titles from Xbox Cloud Gaming. That means a single “Jump back in” row can show your last few sessions across PC, console, and cloud, regardless of where they happened. It’s a subtle but meaningful step toward a unified Xbox ecosystem that follows the player across screens.

Built for Handhelds, but Useful for Everyone

The timing is no accident. With two Xbox Ally handheld gaming devices set for release this holiday season, these features directly address the ergonomic pain points of Windows on small screens. A controller-first launcher that can handle multi-store libraries and launch tools without a keyboard makes Windows handhelds feel more like a traditional console. Even for desktop users, the aggregated library eliminates the ritual of opening three or four different launchers just to see what’s available.

How the Integration Works—and What to Watch

Microsoft says the Xbox app scans for installed games from supported storefronts automatically. The launch process appears to invoke the appropriate store’s executable, so games should behave as if launched from that store directly. However, the company hasn’t published a full technical specification, leaving several open questions:

  • Anti-cheat and DRM: Games with strict anti-cheat engines may behave unpredictably when launched via a different shell. In theory, the Xbox app launches the store’s own launcher, but layered or driver-level anti-cheat systems could flag the unusual call chain. Early testers haven’t reported widespread issues, but competitive players should proceed cautiously.
  • Privacy and telemetry: To discover installed games, the Xbox app must scan your system. What metadata does it collect—file paths, installed store identifiers, usage frequency? Microsoft allows users to hide storefronts from the library, but the scanning process likely still runs. Until the company offers a detailed privacy FAQ, privacy-conscious users may want to keep an eye on what data the app transmits.
  • Installer inconsistencies: In Insider builds, the “My Apps” install flow sometimes failed for certain storefronts, such as GOG Galaxy. Users who encounter problems should install missing clients manually from official websites; the Xbox app will then discover them.

How to Try the New Features

For most people, the update will arrive automatically via the Microsoft Store—just check for updates. If you’re reading this after September 15, 2025, and you don’t see the new library behavior, launch the Microsoft Store, go to Library, and click “Get updates.” If you’re an Insider in the PC Gaming Preview flight, you’ve likely had these features for weeks.

To hide storefronts you don’t want to see, head to Profile > Settings > Library & Extensions and toggle them off.

Compared to GOG Galaxy and Playnite

Multi-store launchers like GOG Galaxy and Playnite have offered aggregation for years, and they remain more customizable with rich plugin ecosystems. But Microsoft’s solution has distinct advantages: it’s deeply integrated with Game Pass and Xbox Cloud Gaming, and it’s built into the default Windows gaming app. For many players, it will be the simplest option that “just works” without installing extra software.

Still, the Xbox app’s aggregation is young. It lacks the metadata editing, game-counting stats, and community plugins that dedicated launchers offer. Power users may stick with Playnite, but mainstream and handheld gamers may find the Xbox app sufficient—especially once cross-device play history matures.

Industry Implications: Convenience vs. Platform Power

By pulling rival stores into its own app, Microsoft positions the Xbox interface as the central hub for PC gaming. That’s a huge convenience win, but it also raises competitive questions. Regulators have scrutinized Microsoft’s platform behavior before; if the company ever gives preferential treatment to its own store or ties advanced features exclusively to Game Pass, rivals could cry foul.

For now, the messaging is one of openness: Microsoft says it will “continue to curate” the My Apps list and expand store support. The real test will be whether it maintains neutrality as the Xbox app becomes more influential.

Recommendations for Power Users and Admins

  • If you value privacy, review the Xbox app’s permissions and consider hiding storefronts or disabling the aggregated library until Microsoft clarifies its data collection policies.
  • IT administrators on managed devices should test whether game discovery interacts with group policies or exposes unintended user data.
  • Competitive gamers should launch titles through their native storefronts for ranked play until anti-cheat behavior is fully vetted.
  • If an installer fails through My Apps, install the store manually—the Xbox app will then detect it automatically.

The Xbox app’s September 2025 update marks a significant pivot: from a Game Pass storefront to a universal launcher. It’s a practical move that can untangle the messy reality of multi-store PC gaming, especially on handhelds. But it also places Microsoft in a powerful orchestration role. How the company balances convenience with openness will determine whether this update is remembered as a welcome unifier or a clever land grab. For now, you can try it yourself—and decide if one library really is better than many.
