Microsoft Store

The Microsoft Store is a multi-platform webstore developed by Microsoft. The Store is natively integrated into Windows 10, Xbox 360, Xbox One, and the Xbox Series X|S, but it can also be accessed from the web. The Microsoft Store offers products, games, and services sold by Microsoft and third parties. If a game is both on Xbox and PC, it may be dubbed as "Play Anywhere", allowing for seamless crossplay and universal save files.
