My start button is stuck at the top left corner and I can't drag it down to
the bottom left. The system tray items are also up there.
So it's not the Start button and the System Tray, it's the *entire*
task bar.
Although by default the task bar appears on the bottom of the screen,
it can be on any of the sides you prefer it on. To move it from any
side to another, simply click on an unused part of it and drag it
where you want it. Be sure to click *within* it, not on the edge;
clicking on the edge and dragging will resize it.
If it won't move, it may be locked. In that case, right click on it
and uncheck "Lock the taskbar," then try again.
I was able to drag
the quick launch items down but not these
The Quick Launch bar is a toolbar, by default on the Task Bar, but it
can be dragged off the Task Bar and docked on another side of the
screen too.
That's what you did. Drag the QL bar back to the task bar before
dragging the task bar to the bottom.
