Add a game to your games list in the Xbox app
Add a shortcut
– Go to Start > Xbox > My games and select Add a game from your PC. If your game isn’t listed and you don’t want to add it to your Start menu, add a shortcut instead.
– Go to Start > File Explorer and enter “%APPDATA%\Microsoft\Windows\Start Menu\Programs” in the address bar, then press Enter.
– In the Programs folder, right-click an empty space and select New, then select Shortcut and follow the on-screen instructions.
– Open the Xbox app and select the refresh button, then select the plus symbol. Choose your game, then select Add selected games.
Pin to Start
– Go to Start > Xbox > My games and select the plus symbol.
– If your game isn’t listed, it probably isn’t pinned to your Start menu. Go to Start > All apps, right-click the game and select Pin to Start. (Alternatively, add a shortcut instead – see other tab.)
– In the Xbox app, select the Refresh button, then select the plus symbol. Choose your game, then select Add selected games.
I did that and pinned Riders of Icarus to my start menu but it still doesn’t show up as an option when I click add a game from your PC. It seems that Xbox doesn’t recognize it as a program
