Will my game progress be saved on both Xbox One and Windows 10 PCs?
Yes. When you play an Xbox Play Anywhere game, your game progress is saved on Xbox Live. So, you can pick up where you left off on another Xbox One or Windows 10 PC, bringing all your saves, game add-ons, and achievements with you.
