Move or Re-position Off-Screen Windows

Occasionally after switching between different screens, when launching applications their window is off the screen and you can't access it. To move the application window back into view, perform the following:

In Windows 10, 8, 7, and Vista, hold down the “Shift” key while right-clicking the item in the taskbar, then select “Move“. In Windows XP, right-click the item in the task-bar and select “Move“.
Use your mouse or the arrow keys on your keyboard to move the window back onto the screen.
