I compared the size of the Start Menu on a 1920 x 1080 display on both operating systems. Even worse, Windows 11 makes you click a second time to see a list of all your apps.
However, in Windows 11, the Start menu is designed to be showy rather than functional, sitting in the middle of the display by default and taking up more screen real estate for fewer icons than in Windows 10. How about some humility, Microsoft? What we want out of Start menu is to give us quick access to all of our programs and then get out of the way.
