Microsoft is making a big change for PC gamers, by integrating Xbox, Steam and Battle.net into a single library. If you're an Xbox Insider, you'll be able to test the new Xbox combined library later this week,

The Xbox App on PC is now integrating purchased games from people's libraries across various supported storefronts, including Steam, Microsoft announced Monday. This feature is currently limited to those in the Xbox Insider program, which gives early access to software updates. Windows users can access the Xbox Insider Hub here .

Microsoft's Xbox app is becoming an aggregator on the PC: soon games from other stores such as Steam can also be launched via the program.
