Windows Store will let you select the install location for large applications and games

The Windows Store will let you select the preferred install location when downloading large applications and games. The feature is going live on Anniversary Update builds.

From Reddit:

You could always choose a preferred location from the Store settings, or move installed content to a different drive. But if you have the OS installed on an SSD and a have a dedicated drive for games, the feature will make it more convenient to download games to a dedicated drive before initiating the download.
