On occasions it may have happened that the title bar of your open explorer window may have moved off screen, ie. your window slides off the desktop, as a result of which you are unable to move the window with the help of your mouse pointer.
Here is a simple tip which will help you move the window in such situations.
Hold down Alt + Space-bar and then press the M key too. Let go all the keys. Alternatively, you can also hold Shift down and right-click on the progragm’s icon in the taskbar, and select Move.
You will see your mouse cursor transform into a 4-way arrow and place itself over the window’s tite bar.
Now use the arrow keys of your keyboard to relocate or move the window.
Right click the mouse when you have moved the Window and are done!
So simple !
