I’m not sure what you mean, the start button on the taskbar? I’m pretty sure it’s always been in exactly the same place and all that has changed is whether it literally says start or not, and what glyph it uses to represent it?
W11 by default centers all taskbar icons, including the start menu. You can change it thank goodness but the default is really dumb.
W11 also has an annoying snap behavior between monitors, which may have led to that decision. My left monitor is 720p and my main is 4K. On W10, I kept the monitors aligned at the top and it made it really easy to land on the bottom left corner of the main screen. Now it jumps up to the left monitor doing the same thing.
Windows 8 made it a gesture to activate the start menu… rather than clicking a start button.
