Let me clarify; For example when I wanted to install Google Chrome, I downloaded the Installer(Launcher I guess) for chrome. Then when I clicked on it it took about half an hour to open up and ask me for admin permissions. At first I thought it was maybe just with chrome but I tried another program for instance the setup for FarCry 5. It was the same story again, it took ages to open up. The problem only recently popped up.
