The problem with these “settings” is that Windows updates don’t respect them. They frequently get reset or superseded by new updates. This happened constantly if you tried to disable Cortana in Windows 10 - even if you changed the registry settings manually, they would get overwritten during updates. I don’t trust Microsoft to respect user choice, they have a demonstrated track record of ignoring it.
