You did not read the request properly. They asked to move the task bar to the left side of the screen, which is now impossible in Windows 11. Thank you morons at Microsoft. Your procedure simply ALIGNS the contents of the task bar either center of left WITHIN the task bar, which is FIXED in position to the bottom of the display.
In Win10, the task bar could be positioned on the left side (left edge) of display.
Absolutely ridiculous this option was removed. Trying to force the Apple/MAC appearance on us.
