How to move an off-screen window back to your desktop in Windows 7
In previous version of Windows before Windows 7, you can just right click on the application Icon on your taskbar, select ‘move’, and then use your keyboard’s left/right/up/downdown arrow key to move your window to the centre of your desktop.
Starting from Windows 7, right click doesn’t bring those option up any more. You have to press shift and then right click on the application icon, select ‘move’, and use arrow keys to bring the window back.
