Adobe Express Photos auto install???

I went to print a screenshot today, and all of a sudden my Windows print screen key has been taken over by an app that I did not install “Adobe Express Photos”. That is infuriating. How could you do this, Adobe? As I search for answers here, I'm finding I have to go into my Windows registry to stop it. That's ridiculous. I'm not a computer programmer, and I shouldn't be messing around with my own registry to delete something that you guys are auto-installing. Please fix this behavior, Adobe. This is maddening, really horrific. Unwanted programs that auto-install themselves are typically considered to be viruses, aren't they?
