How to hide real name and email address on Windows 10 Lock Screen
For privacy and security reasons you may decide that you do not want to display your real name and your email address on your Windows 10 lock screen, where you enter your PIN or Password to sign in. This post will show you how to hide your real name and email address in Windows 10 Lock Screen using Group Policy, Registry – and via Settings app too, from Build 14328 onwards.
Hide real name & email address on Windows 10 Lock Screen
Using Group Policy setting
Run gpedit.msc and navigate to the following setting:
Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options
Double-click on Interactive logon: Do not display last user name settings and select Enable.
This security setting determines whether the name of the last user to log on to the computer is displayed in the Windows logon screen. If this policy is enabled, the name of the last user to successfully log on is not displayed in the Logon Screen.
Click Apply and exit.
Using Registry Editor
Run regedit and navigate to the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Policies\System
In the right pane, double-click on dontdisplaylastusername and change its value from 0 to 1 as shown below.
DontDisplayLockedUserID
You will also see a DontDisplayLockedUserId key there. The possible values for DontDisplayLockedUserID are:
1 : Show the locked user display name and the user ID
2 : Show the locked user display name only
3 : Do not display the locked user information
Select 2 or 3 depending on your preference, save the settings and exit the Registry Editor.
Windows 10 will now hide your real name and email address on the Lock Screen.
In Windows 10 Anniversary Update Build 14328 and later, you will now be able to easily effect this change. You will get this setting under: Settings > Accounts > Sign-in options > Privacy > Show account details on sign-in screen.
