If you’re looking to add friends on the Xbox app for Windows 10, there are a few different ways to go about it. The first is to use the search bar at the top of the app and type in someone’s name. If they’re already signed in, their profile will show up with a blue dot next to their name. If they’re not signed in, you can sign in using their Gamertag or Email address. Once you’ve found them, click on their name and then select “Add Friend.” If you want to add someone who isn’t already on your friends list, you can do that too by clicking on the “People” tab at the bottom of the app and selecting “Add Person.” From there, just enter in their name and email address and hit “Add.” ..
