Disc to Digital Licensing on XBOX
Disc to digital licensing on XBOX is a new way to make many of your disc-based games easier to access wherever you play. When you use an eligible XBOX One or XBOX Series X game disc, Microsoft may grant a digital license associated with that disc. This allows you to access supported digital versions of the game without keeping the disc inserted while playing.
