I would like to view photos in Windows 10. Unfortunately, when I double click on a photo it is displayed in a window of the Photos app with a black border. However, I don't want to waste space for a borer but I only want to see my photo as large as possible.
How can I get rid of the border?
(Switching back and forth between full screen and window mode is annoying because of the additional key strokes and therefore not an option for me.)
