Choose TuneUp as a Windows 11 default music player

Install TuneUp first.
In File Explorer, select a music file such as an MP3. Press Shift+F10 and choose Open with, then Choose another app. Select TuneUp and choose Always when offered. If TuneUp is missing, choose the option to select an app on your PC and browse to:
%LOCALAPPDATA%\Programs\TuneUp\TuneUp.exe

Alternatively, open Settings, Apps, Default apps. Search for TuneUp or a file extension such as .mp3, and choose TuneUp for that extension. Repeat for .wav, .m4a and any other formats you want.

Windows controls your default-app choices; the installer registers TuneUp as an available choice. Once selected, Enter on a music file launches TuneUp, adds it to Main playlist and starts playback. New files opened while the main TuneUp screen is open are sent to the same instance. Close an open TuneUp dialog before doing this.
