Do you find the floating volume rectangle annoying? You can remove Volume OSD floating in Windows 10 or replace it with Windows 11 OSD.

If Bluetooth Speaker Volume Control not working and you cannot adjust the volume of a Bluetooth speaker in Windows 11/10, do this to fix the issue.

That's where individual app volume control comes in. Right out of the box, Windows has its own built-in options for making your own volume mix on your desktop or laptop.
