A trick with moving the taskbar is to right click and uncheck Lock the Taskbar. This lets you drag it to the top or sides and also lets you drag it from one monitor to another to change which one is the primary display.
Dragging the taskbar is very handy if your company uses Remote Desktop and you need to window RD. Then you can’t access taskbar at the bottom and at the top it sometimes gets in the way of the display bar so you often have to move it around as needed.
Changing primary display can be important if you’re using something like Citrix and then program notifications (like, oh god, MS Teams) don’t show up because they are “behind” Citrix. The only thing worse than hearing a Teams call ringing is also having no idea who is calling you lol
