If that computer is running Windows 10, it isn’t your computer. It belongs to MS and they’ll do what ever they please with it.
Like not allowing you to log on until they are satisfied it is “updated”.
You notice over the years, the "My Computer" icon got renamed "Computer", and then "This PC". That's a hint. Even Microsoft admits, it's not your computer. It's just this PC that you're sitting in front of. Most of the time, you might as well be downtown at the Library in front of a terminal.
