Once you select an App from the pop-up menu (Say Windows Media Player), it will become your default music player in Windows 10. In the pop-up menu, select iTunes, Windows Media Player or any other Music App that you want to use on your computer. In the right-pane, scroll down and click on Groove Music. Go to Settings > Apps > select Default apps in the left-pane. If you do not want to use Groove, you can change the default music player on your computer to Windows Media Player or any other Music Player of your choice. Groove is closely integrated with Microsoft’s cloud storage service and allows users to upload music to OneDrive and access the same on any device – Windows computers, Xbox consoles, iPhone or Android Phone.
