My kids somehow moved the start bar from the bottom of the screen to the
right side. How do I get it back down to the bottom?
First, note that it's called the Task Bar, not the Start 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.
