I just opened Wunderlist (the one from the Windows store) and the top half is off-screen. Right-clicking the icon in the task bar and selecting move no longer works, since it's not there. Accessing the move command in the menu bar through the keyboard as suggested here doesn't work.
How do I get it back on screen? (and why is this still an issue, so many years later?)
Sometimes it is impossible to right click the runaway window so none of the other solutions here work. The only foolproof method that I found ALWAYS helps is to find the process in task manager, click on the arrow to expand the application dropdown, then right-click the process and select "maximize window".
First activate the window by clicking on it on the taskbar and then press the Windows logo key on your keyboard together with the left or right arrow key.
If the window was minimized, you have to press Windows logo + arrow up key.
Resizing the window from the bottom and dragging it to the edge of the screen to activate the snap function worked.
