Say I have 2 finder windows open, A and B.
I begin focussed on A, then
⌘ + ~ to focus on B, finally
⌘ + ~ once more, and it still leaves B in front, but B is now slightly grayed out (same style as finder window A when it's behind other finder windows).
This 3rd location is focussed on the Desktop, how do I prevent the Desktop from receiving focus on
⌘ + ~? I only want actual Finder windows to receive focus?
To prevent the Desktop from receiving focus on ⌘+~, you will need to change the shortcut for Finder's menu option
Cycle Through Windows.

Note: ⌘+⇧+` will then be your ⌘+~ and will be for
Move focus to *previous* window shortcut.
