If you’ve ever had a window somehow get moved off your screen, you know it can be frustrating not being able to drag it back. We’ve got a couple of ways you can move these rogue windows back to your desktop, though.
The easiest way to get back a hidden window is to just right-click on the Taskbar and select one of the window arrangement settings, like “Cascade windows” or “Show windows stacked.”
The “Cascade windows” setting, for example, will immediately arrange all open windows in a cascade, moving all windows back onto the main screen in the process.
After you’ve got the window active, Shift+right-click the taskbar button (because just right-clicking will open the app’s jumplist instead) and choose the “Move” command from the context menu.
At this point, note that your cursor changes to a “Move” cursor. Now, you can use your arrow keys to move the window. You should also just be able to tap any of the arrow keys and then move your mouse slightly to have the window pop back onto the screen.
