Logon Screen shows 2 users but there is only 1 user

On a friends laptop which was given to him, on the startup/logon screen he sees 2 names. His own and the
previous owner.

He said he deleted the user account for the previous owner and if I go to users, it only shows him as the sole
user as administrator.

If I use the netplwiz command to try an hide the original user, it only shows the new user and I think it was
users/workgroup. The Users/workgroup is greyed out so I cannot change or delete this user.

If the original user account who was the administrator was deleted, why is her name showing up
on the logon screen?

This laptop is running Win 10 Home.

Assistance needed to show only current user/administrator on the logon screen.

There is a little trick to removing ghost users from the login screen, I can't remember exactly which option it is in netplwiz that needs to be cycled between off and on but there are only two. Under the advanced tab, check the box for "Require users to click CTL-ALT-DEL", click apply, then uncheck it again and click apply.

Under the Users tab, uncheck the box for "Users must enter a username and password..." Click apply. Click cancel on the window that appears. The checkmark in the box for "users must enter a username and password...." should have an X again automatically. Click apply with it checked again. Then exit NETPLWIZ.

Yep, that worked. A few little differences, but basically, I enabled everything, applied it, disabled it, applied it, rebooted and presto. No ghost user.

Thanks

Hi
I was having the same problem with duplicate user login accounts one with a picture and one without both with my name although I only had only one user account with my name in settings. Setting Netplwiz to auto login would try to login the user with no picture and receive an incorrect password error tried my pin but did not work. I then clicked on the user with a picture and used my pin to login.
I finally figured out what was happening the user that first came up with no picture after setting Netplwiz to auto login needed to be logged in with my Microsoft account password not my pin I entered that in Netplwiz. After that autologin now works.
