Cross Device Platform Question

But I already have something for PDF's, and I shut it off, but crossdeviceresume now appears. Why can't we just have our computers back? I am getting sick and tired of taking folders away from "Trusted Installer" and "System" and anything else Windows decides I don't need to access on my own computer. It is like having a safe in your house, that you don't know the combo to, for your neighbor down the street to put his stuff in. It makes no sense. I have noticed through the years how we have slowly started to lose easy access to our own computers. I am just waiting for the day that we have no access, can't bypass the microsoft account for a local account, can't take off anything, and it won't work unless it is connected to the internet.
