If you have always hooked up your laptop to a secondary monitor and then disconnected without remembering to move the windows back to the primary desktop, you have possibly face this issue:

The application is running. You can see it in the taskbar, but you can not see it on the screen, because it still imagines it is running on the secondary monitor. You attempt and use right-click, Move, but that does not perform anything, and the window does not move anywhere.

There is a easy method to find approximately this. First make confident you have alt-tabbed to the window, or clicked on it once to bring it into focus. Then right-click on the taskbar and select Move.

At this point, you must observe that your cursor changes to the “Move” cursor, but you still can not move anything.

At present click on any one of the arrow keys (Left, Right, Down, Up), move your mouse, along with the window should magically “pop” back onto the screen.

This should work on any version of Windows. It is really wonderful how many people are not conscious of this little trick.
