How to Hide User Account from Windows Logon Screen?
Displaying the account name on the Windows login screen is convenient for users, but reduces the computer security. An attacker who gained local access to a computer will have to pick up only a password (for this there are various ways of social engineering, brute force attacks, or a banal sticker with a password on the monitor).
You can hide the last logged user name on a Windows welcome screen through the GPO. Open the domain (gpmc.msc) or local (gpedit.msc) Group Policy editor and go to the section Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options. Enable the policy “Interactive logon: Do not display last user name”. By default, this policy is disabled.
Also, you can hide the username on the login screen through the registry. To do this go to the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System, create a new DWORD parameter named dontdisplaylastusername with the value 1.
Additionally, you can hide the username on a locked computer. To do this, in the same GPO section you need to enable the policy “Interactive logon: Display user information when the session is locked” and select the value “Do not display user information”.
A registry parameter named DontDisplayLockedUserId in the same registry key with a value of 3 corresponds to this policy setting.
Now on the computer login screen and on the Windows lock screen, an empty fields for entering a username and password are displayed.
