Closing the app will still run mute

[mnba3223]

Hello, after I close the mute application, it will directly mute the sound when I run certain games (I have not added it to the whitelist).
I confirmed that WinBGMuter is no longer running.
This will also happen when restoring to default values.
I feel like this setting will remain in place?
Or is there any way to completely remove this program?
