Can you show the screenshot?I run command "netplwiz" however, the option to toggle that setting is not there.
unfortunately that option is totally missing and I dont see it on any of the other tabs on that "user accounts" window.
The only password related option on that window now is to change passsword by "ctrl+alt/delete" but the "reset password" button is greyed out.
I recently reinstalled W10 and noticed this after first reboot while I was adjusting all my settings.
Check solution from this thread:None of that Windows Hello junk is turned on.
