How to fix new User on login page.

Today I tried to use my computer which has several user accounts on it. Only the last used account was showing up on the login screen. So I followed a tutorial online to fix the issue.

In the tutorial below I did step one.

It gave me the option to sign in using a web account but I didn't know the password. Microsoft barely even uses passwords anymore. Anyways I decided to reverse what I did so that I can start over. So I typed in the same exact command but changed yes to no. Now at the sign in page it just lists the account name as new user. I obviously don't have the password for this account. From what I've read online once you get to this point the computer essentially needs a complete reset. Is that still the case?
