In Windows 10, Edge is the default web browser, Groove Music is the default music player, and Edge is the default PDF reader. If a user wants to change one of these default apps, s/he can navigate to Settings > System > Default apps.
Although most users can change the default web browser, default PDF reader, and other default apps under the Settings app, there have been reports that Windows 10 doesn’t allow changing default apps at times.
If you’re also unable to change the default web browser, unable to set VLC as the default video player or unable to set any other program or app as a default, you can use one of the two given below methods to change default apps or set your favorite third-party program/app as your default program in Windows 10.
