Hey Monado,
Option 1:
Yes, this is possible. Some Accounts have Cloud Saving for Saves (This includes single player saves, so it can just transfer as soon as you boot the game.
Option 2:
The more "guaranteed" method in my opinion, is making your save a "Shared World" this will 100% transfer to PC and all platforms associated with the Xbox Account.
