"Question. I noticed your resolution is 1920 x 1080. Will this work at 1366 x 768?"
Yes it will work. You will not have to adjust anything like ALMonty said because everything is set to "keep on screen" and "snap to edges", also everything is dragable so just place stuff where you want.
You can also open up the bars image folder and simply resize them if you want but that should not be necessary.
By the way, clicking on the "view" option will hide and show the taskbar and start menu.
