Hi Roger
I am Dave, I will help you with this.
There is no global setting in Windows 11 to remove that media bar, it can only be done on an app by app basis:
1
Chrome
Open Chrome
In the Address bar, paste this and hit Enter:
chrome://flags
On the resulting page, type media key in the search box
Disable 'Hardware Media Key Handling'
Restart Chrome
2
Edge
Open Edge
In the Address bar, paste this and hit Enter:
edge://flags
On the resulting page, type media key in the search box
Disable 'Hardware Media Key Handling'
Restart Edge
3
Spotify
Go to Edit - Preferences
Scroll down to the bottom of the basic settings
In the Display Options, turn off 'Show desktop overlay when using media keys'
