When you start your Windows 10 computer, the following error appears. Also, duplicate user accounts may appear on the login screen.
The user name or password is incorrect. Try again.
After you click the OK button, you’re prompted to enter the correct password. Also, you’ll notice that a duplicate user account of the same name appears in the lower-left corner.
This issue is seen in computers that have automatic login enabled. On the computers where auto-login credentials are stored, the error
The user name or password is incorrect. Try again and the duplicate user account may appear on the login screen due to one of the following reasons:
- You have changed the computer name recently. (or)
- You have changed the user account password recently.
When you enable automatic login by saving your credentials (via
netplwiz.exe), Windows stores the user name, password, and the computer (domain) name in the
Winlogon registry key below:

So, if you’ve changed the account password or the computer name after configuring automatic login, the system fails to auto-login to your account and shows a duplicate user account icon.
To prevent the duplicate user account from appearing and also the error “The user name or password is incorrect” at startup, clear the automatic login credentials, and then configure it again.

All you need to do is change the
DefaultDomainName registry value, mentioning the new computer name.
