I recently read that running Windows (10 Home, in my case) primarily on an administrator account is a bad idea for security reasons. So, I created a local account to work in, and I'll only log in as an administrator as needed.
My administrator account displays my real name on the sign-in screen. I'd like to change this to just "Administrator" or "Administrator Jack" to differentiate the two accounts, since my local account is also my full name.
I can't figure out how to do this. I logged into my Microsoft account, which is linked with the machine's administrator account, and changed my name there, but the change has not taken effect on the sign-in screen; it still shows my full name.
What do I need to do to make these desired changes?
