Hi WVMike,
I am Dave, I will help you with this.
In Windows 11, they have created a new File Explorer app and it is not possible to get that to look like Windows 7, not even with a 3rd party utility, because that app is so new, it will take tie for software developers to be able to change that app.
To make the navigation pane more like a slightly older version, right click an empty spot in the navigation pane and turn on 'Show all folders'
