Strange variation on The username or password is incorrect"


I recently changed my computer's name and now get "The username or password is incorrect" on startup.

Note that if I change the name back to the earlier name the problem goes away, so the name changing appears to be the cause.


More detail:-

With the new name, when I startup I see the welcome screen for a moment and then the error message appears together with an OK button. When I click OK, there are two instances of my name in the bottom left corner of the screen; it wants to sign in with a new "unwanted" one. If I select the "normal" one I can then enter my password and will be logged in with my Microsoft account credentials. But note that I haven't needed to do this until now as I have de-selected "Users must enter...." in netplwiz.

If I select the "unwanted" one I can sign in with my Microsoft account credentials which only achieves the same as the normal one with the extra requirement of needing to type my email address as well as my password.

Obviously, I want to be able to bypass this step altogether as my use of netplwiz demonstrates.


I have tried all the solutions I have found in sites like

and am now totally at a loss.

I'd be very grateful if anyone is able to help.

 

Strange variation on The username or password is incorrect"


To log in automatically, Advanced User Account Control Panel (netplwiz) stores your username as \\ComputerName\UserName.

Let's say your computer name is PC-1 and username Alan, netplwiz will save it as \\PC-1\Alan. If you now change your PC name to PC-2, your username will be changed, too, it being now \\PC-2\Alan. However, netplwiz is still trying to log you in with \\PC-1\Alan, a username which does no longer exit.

Solution which should work is to select Users must enter a username and password in netplwiz, restart and log in with password, then unselect Users must enter a username and password in netplwiz. Automatic log in should work now.

 

Username or password incorrect


I've previously run netplwiz from the command prompt to disable the sign in process in Windows 10.




Which worked fine in build 10049 but in 10158 & 10166 I now get this error message





I don't understand how this message can appear as no password has been entered at this stage.
Pressing OK, or waiting 2 minutes results in this screen





Entering the PIN or password from the sign-in option continues the login process.
Apart from starting again from scratch, any ideas on how to correct this.
