If you own a digital copy of The Long Dark on Xbox, it’s also available for you to play on the Microsoft Store for Windows 10. Simply log in using the same credentials you use on Xbox and install The Long Dark on your PC to continue right where you left off.
As long as you’ve signed in to both platforms with the same account, save files will sync between your Xbox and PC. Keeping both applications up to date will prevent issues with incompatible save file versions.
