Not sure why Microsoft needs separate stores for Windows apps, music, and videos? Neither is Microsoft… so the company is bringing them all together into a single Store.
If you’re running a recent preview of Windows 10 just fire up the Windows Store app and it’ll download an update, relaunch, and show you a new store that has sections for Apps, Games, and Movies & TV.
Microsoft plans to add a music section within a few weeks.
For now you can download the latest preview versions of the Music and Video apps for Windows 10 which will be integrated with the Store at a later date.
Among other things, the unified store will give you a one-stop shopping experience when looking for digital content sold by Microsoft (much the way the Google Play Store already does for Android users).
Since your downloads and purchases will be tied to your Microsoft account, you’ll also be able to install free or paid apps, rent videos, or buy music on your PC and access the same content on a Windows Phone, Xbox One, or other supported device.
