Microsoft quietly pulled another bit of Windows into the Xbox tent this week. On September 15, 2025, the company began rolling out an updated Xbox PC app that no longer only shows Xbox and Game Pass titles — the app will now list and launch games you’ve installed from Steam, Battle [.net], Epic, GOG and other PC storefronts. In short, the Xbox app on Windows is trying to be the launcher for everything you already play.

What changed

If a game is installed from a supported store, it will now show up in the Xbox app’s My Library and in the Most Recent sidebar, and you can launch it from there. Microsoft says you can toggle which storefronts appear in your library if you want a tidier view. The company also added a new My Apps tab so you can install or launch third-party apps (think: other storefronts, browsers, gaming utilities) from the Xbox app itself. These changes are being shipped as a general rollout to Windows users now — the features were tested with Xbox Insiders beforehand.

Jason Beaumont, Xbox’s vice president of experiences, framed the rollout as part of making the Xbox app a single place to manage and jump back into games: “When you install a game from a supported PC storefront, it automatically appears in ‘My Library’ within the Xbox PC app,” he wrote on Xbox Wire.

Why this matters (beyond convenience)

On the surface, this is a tidy UX improvement: fewer launchers to click through, a unified “most recent” list, and faster access on devices where switching between windows is awkward — most notably, handheld PCs. But the move also has broader competitive and strategic implications:

• A stronger Microsoft hub for PC gaming. Centralizing installed games makes the Xbox app more valuable and more sticky — it’s not just a Game Pass storefront anymore, it’s a one-stop play surface for the PC. That helps Microsoft position Xbox on Windows as the default gaming experience for people who use multiple stores.
• Less friction for handhelds. The feature is explicitly aimed at full-screen handheld experiences (like the ROG Xbox Ally devices Microsoft has been promoting). Aggregating titles into a single library reduces the pain of launching a game on small, controller-first screens where having five different launchers is a nuisance.
• Where third-party launchers fit. Microsoft’s “My Apps” page will even let you pin or launch rival storefronts, which looks like a nod toward keeping an open ecosystem while still centralizing discovery and play. That’s a pragmatic approach: users still need Steam’s account features, friends lists, DRM and sales — Microsoft is just making it easier to run them from one place.

What gamers and power users should know

There are some practical details and limits worth flagging:

• It shows installed games, not necessarily full account integration. The app detects installed titles and surfaces them; it’s not replacing Steam or Battle [.net] accounts, achievements, or game-specific overlays. If a game needs a launcher to run, the Xbox app will hand off to that launcher as needed.
• You can control what appears. If you don’t want every third-party game listed, Microsoft added settings to toggle storefronts off in the Library & Extensions area of the app. That should ease privacy or clutter concerns for people who want to keep a lean library.
• It’s not an immediate threat to Playnite or similar tools — yet. Community tools that track games, metadata and uninstalled titles will still have reasons to exist (and they often do deeper cataloging). But for users who mainly want a single launcher to open installed titles, the official app now covers a lot of ground.

What’s coming later this month

Microsoft says a follow-up update arriving later in September will add cloud-playable filters and cross-device play history — so your “Jump back in” list can follow you from console to PC to handheld, and you’ll be able to filter your library for titles you can stream instead of download. That feature set is being tested on consoles now and is headed to PC and handheld soon.

The broader picture: consolidation without collapse

This rollout fits within a long trend: platform owners want to be the home screen for your entertainment. Microsoft’s edge is that it already makes Xbox hardware, Windows, the Microsoft Store and Game Pass — stitching those together around a single app gives the company more consistent touchpoints with players. Critics will watch for subtle nudges toward Microsoft commerce (promotions, Game Pass upsells), but for the average player, the immediate win is fewer windows and one place to look when you want to play.

For people who like tweaking and deep cataloging, nothing in this update removes existing options — it just gives a Microsoft-backed and potentially more controller-friendly way to access everything you’ve already installed.

Bottom line

If you’ve ever double-clicked the wrong launcher, forgotten which storefront holds a game you want to play, or wrestled with a mouse-first launcher on a tiny handheld screen, this update will feel like a small but meaningful quality-of-life win. It’s also a clear signal of Microsoft’s playbook for PC gaming: centralize the experience, make cross-device play feel seamless, and keep as many players as possible inside Xbox’s orbit — whether they buy games from Microsoft or not.
