How to change default size when opening an acrobat doculent
with Win 10, Acrobat 2017, when I open any PDF, it displays a gigantic version of the document. How can I change the default size from what it is (probably something like fill the screen so that you can't see it all) to something useful, like 75%?

for example: instead of opening at this 165%, let me change it to 50 or 75%
