Position the cursor in the body of the taskbar, not on the edge (where cursor appearance changes to double ended arrow) before dragging the taskbar down.
Sounds like you dragged the whole taskbar from the bottom of the screen to the right side of the screen. Just click the taskbar, hold the mouse button down, and drag the taskbar down to the bottom of the screen before letting go.
Right-click on your taskbar, if a tick is next to the Lock taskbar option, make sure it is disabled. After that click and drag your taskbar to the bottom or top of the screen.
Drag it to whichever side of the screen you want it. If it is locked, you have to unlock it before you can move it.
If you are using windows I'm guessing you are talking about the bar with your start button. That whole bar can be clicked on and dragged to any side of the screen. If it won't move, right click it then select "lock the taskbar" and it will unlock it for you to move it. After you move it where you want, right click it and once again select "lock the taskbar" and it will stay there. Hope this helps!
In order to move your taskbar to different sides of the screen, first right-click on the task bar and click "Lock the Taskbar". By default, Windows will automatically lock the taskbar in place to prevent it from accidentally being dragged. Next click and drag it in the direction that you want. When you have it positioned, right click and select "Lock the Taskbar" to keep it where you have it set.
It's called 'show desktop' - it tells you that if you hover your cursor over the tiny vertical bar at the right end of the taskbar.
Right click on taskbar, the click on "Lock the taskbar".

on the taskbar right click on it and select lock the taskbar and when you do it again it should be checkmarked
The taskbar (containing the Start menu, running programs, Quick Launch and System Tray) can be positioned on any side of the screen, across the top, vertically down either side or along the bottom of the screen (which is where most people have it). If you've chosen to autohide it, simply move the pointer close to the relevant screen area and it will re-appear. If you right-click on a blank area of the taskbar, you can chose Properties which allow control over its behaviour and content.
A taskbar is used for reseting the whole computer
If you use the unlock option you will still have a narrow blue line at the bottom. But the taskbar basically would be hidden. If you use the autohide option the taskbar will hide completely automatically. But when you move the cursor at the place where the taskbar suppose to be the taskbar will pop up.
