Beyond habit, there is a practical efficiency argument rooted in Fitts’s Law, a principle of human-computer interaction which states that the time to acquire a target is a function of the distance to and size of the target. While a centered Start button is easy to see, a left-aligned button is easier to hit because it is "pinned" to the corner of the screen. On a standard multi-monitor setup or an ultrawide monitor, the bottom-left corner is the easiest point on the screen to target; the user simply throws the mouse as far left and down as it will go, and the cursor stops exactly on the button. A centered button requires precise tracking and stopping, which, while minor, adds cognitive overhead to a frequently repeated action.

You can easily restore the classic left-aligned look through the Windows Personalization Settings : any empty space on your Taskbar . Select Taskbar settings from the context menu. windows 11 start menu left
