If you are a hardcore PC gamer, one of the issues that will surely affect you is the need to download and sign up for the current Digital Game Buying Accounts available, including Steam, Epic Games Store and more.
Recently, Microsoft has updated the Xbox app to enable it to list a variety of games you already have from other purchasing platforms, including Battle.net, Steam and Epic Games Store.
Once you update the Xbox app on your PC, and you've logged in to Steam, Epic and Battle.net accounts, games already installed on your computer will be listed on the My Library tab immediately.
You will need to make sure that you have already signed into Steam, Epic and Battle.net accounts first before the games are listed. For DRM confirmation purposes, these accounts will also need to be active in the background before they can be played.
You can update your Xbox app today to use this feature.
