Hi,
Thank you for writing to Microsoft Community Forums.
We understand the concern as you would like to reinstall the game and want to know if the game progression will be retained.
In this scenario, we would like to inform you that once you install a game and sign-in with the Microsoft Account and play the game and later reinstall the game, then you need to sign-in with the same Microsoft Account to retain the game progression where you left. So make sure that you have logged in to game before reinstalling the game.
Regards,
