I am well-acquainted with all the ways to do it. That's beside the point. I won't re-post what I already posted in bulleted form, but, when I upgraded to Windows 10, Microsoft made changes without my permission, importing my photos, documents, email pst and ost files etc to OneDrive, and then blamed me for incompatibility with OneDrive and tried to get me to purchase larger storage to accommodate their movement of all the "library" directories to OneDrive. ALL without my permission. I never wanted them on OneDrive.
The Photos app and the libraries sync to OneDrive, EVEN WHEN I UNINSTALL ONEDRIVE. Any time there is a Windows update, that defaults their way, over and over again, and I have to manually change it. EVERY TIME.
I plug in a device, such as my phone, and even when I have unlinked it permanently from Photos, it STILL wants to sync with Photos via OneDrive. When I bought earlier versions of Office, I got OneDrive along with it, including a promise that I would not have to pay anything for storage, and that OneDrive would remain a part of it. They lied about that. There are a number of really good articles about this scam from Microsoft.
The evidence is overwhelming what people want, but Microsoft is too obtuse and stubborn to honor what people overwhelmingly want.
I am being compensated for some of their excesses regarding Windows, Office, etc. in a gigantic class action suit. I will be watching for a hawk for the next round, which will undoubtedly involve the way they are manipulating their product and my use to force us into the way they want, once again. I will be watching for their practices on Edge, Cortana, libraries, aps, file explorer, indexing, and more. Maybe they will start paying attention if people pay attention to the class action.
I have gotten quite angry with them, because they give me a shut up response to every legitimate inquiry. The end of the discussion is the one that invites ALL of the class action: "We're sorry you feel that way, but that's the way it is, and we can't help you."
In summary, it ought not be what we have to do to circumvent their hijacking of our organization of our own data and control of our own data. They simply don't have my permission to do that. And the courts will keep reaffirming that they can't take a stranglehold on our use of our computers and our data.
