Usually, when I open a desktop icon, the image occupies the full screen, but lately I am only getting a small image (plse see attachment) about 4 ins x 6 ins in size (or postcard size), which means I have to click on VIEW in the said image and then choose FULL SCREEN in the dropdown menu. This is annoying.

How to revert to my old practice without the bother of having to go to VIEW every time I open a desktop icon?

I use Windows 10 and a laptop computer.
