I guess my point is that most users spend very little time actively using Windows. When my computer is on, close to 100% of my time is spent in the browser or Visual Studio or email or some other program that requires Windows. I spend very little time in Settings, the Start menu, the device manager, etc.. I would guess File Explorer is my most used part of Windows.
So how do you use Windows? Isn't it essentially a foundation for the applications you want to run? Is the percentage of time you spend doing OS level things significant?
