Move an Application Window From Off-screen Back to Your Main Desktop - Windows

Occasionally, Microsoft Windows thinks you have a second desktop/monitor when you don't. Or, you do have a second desktop/monitor but it is currently not working or can't be turned on. The technique below allows you to bring a window from the "invisible" desktop back to your main desktop.

1. Right-click on the Windows taskbar and select Cascade windows from the pop-up menu.
2. Hold down the Shift key, then right-click on the appropriate application icon in the Windows taskbar.
3. On the resulting pop-up, select the Move option.
4. Begin pressing the arrow keys on your keyboard to move the invisible window from off-screen to on-screen. Typically, you will use the left arrow to move the window from right to left.
