I need help with something. My computer's toolbar is messed up and now it's on the top for some reason. Does anyone know how to get it back to the bottom?

An advice from me - stop using any toolbar.

Maybe he is referring to the taskbar, the one where Start menu is. If that's the case, right-click it and unlock it. Then move it as you like, and lock it again.

If it is a explorer toolbar (The Address bar, the File bar or the Navigation bar) do the same: right click it, unlock, move and lock again.
