Hi Craigmore,
I wouldn't take a step back when something is done without permission, on a tool/machine that is supposed to be private, for my own use only and is located within my own home. The right thing to do is to ask first, and definitely not integrate it so deep in the system.
Thank you for your reply, but it didn't work, as OneDrive was allegedly removed but actually metastasized all over my computer (Photos, Documents, Desktop, etc.), even after following your solution "to a T".
The only thing that had worked was following the solution offered in the link bellow, via Registry Editor (and after allegedly removing OneDrive), with the many helpful screenshots, which I am describing for others who might need it:

Good luck to everyone else!
