By default the position of taskbar in windows is at the bottom. But if you want to change it then you can do it as you like.
There are two ways by which you can do this.
Right click on the taskbar and click on “properties” from the menu.
Then click on “Apply” and then on “OK”
Now your taskbar will appear at the top.
The other way is to click by pointing mouse pointer to the taskbar and hold the mouse button. Then drag the taskbar with mouse pointer to which location you want.
Remember that if “Lock the taskbar” option is clicked then the taskbar will not move.
Right click on the taskbar and check whether “Lock the taskbar” is selected.
