Microsoft Updated its New Xbox Beta Application in Windows 10 to Add New Account Linking Options Announced time on the Inside Xbox last week. You can now link your Steam, Facebook, Twitter and Twitch accounts from Settings and choose whether you want to display these accounts to third parties on your player card.
This feature is also available in the Xbox gamebar for Windows 10, where you can also connect your Spotify account if you want to control the playback of music from the Xbox gamebar while playing.
 Linking your accounts will also let you find your Steam and Facebook friends who also have Xbox Live profile, in addition to basic Xbox gamertag search functionality. Microsoft announced on Xbox Wire last week that there would be more options for linking accounts, including YouTube, Reddit and Discord. It is worth noting that the latter already allows users to link external accounts and unlock special Discord integrations.
In the Xbox beta, the latest update also added the ability to support Mixer Partner when you join the Xbox Game Pass. You can do this by clicking the new "Support Creator" button below your account icon. You will need to enter the Mixer Partner code into the application and we have not yet been able to test it, as this is currently limited to new Xbox Game Pass subscribers or existing members upgrading to the Ultimate level.
Last but not least, the Xbox Beta app has also been updated with new ways to find and filter games , as well as other controls over download management. The app is quickly becoming an essential tool for Xbox Game Pass subscribers, and it also has some nice messaging features. However, it probably won't replace an app like Discord for hardcore gamers.
