The Start Menu has been a renowned feature of the Windows operating system since its inception during the Windows 95 era.
Microsoft decided to integrate a middle default alignment of the Start Menu in Windows 11.
This is in contrast to previous versions such as Windows 10 where the Start Menu is identified with a left default alignment.
To change the Start Menu alignment, simply go to the taskbar and right click.
Click the Taskbar settings dialog box that appears then wait for the Settings page to open.
Scroll down to the bottom of the page and click the down arrow to the right of Taskbar behaviors.
Scroll down a little further and then select Left instead of Center after clicking the down arrow on the box located to the right of Taskbar alignment.
