Windows 10: 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.

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.

 

Username or password incorrect


I agree that the lock screen is useless, pressing any key raises it to reveal your email!
They should hide the email!
You can, however, login in to OneDrive and edit your moniker and create an alias email, which doesn't exist and is not verified.





(I blurred it anyway even though it's a BS email)

 

Incorrect password or username

Hi, everytime I try to install a programme of some sort I get a pop up that requires my password and username, when I enter my credentials it tells me they are incorrect. Please help on how to sort this issue out. I literally do not require a password
for my login so I don't know what the problem is. I would appreciate some help
