Hide your email and user name from Windows 10 lock screen

Previously, we covered how to hide the last logged in user's name in Windows 10 from the sign in screen. Once you had applied that trick, you had to type your user name and password every time you signed in. But when you lock your Windows account using Win + L and walk away, some private details are still shown there. Many users are asking me how to hide these when you lock your PC. Hiding account details is especially useful when you are using a Microsoft Account because it exposes your email address. In this article, we will see how to hide the account information displayed when you lock your PC in Windows 10.

To hide your email and user name when you lock your account, you need to do the following:

1. Open Registry Editor.
2. Go to the following Registry key:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

   If you don't have such a key, then just create it.

3. Modify the 32-bit DWORD value named dontdisplaylastusername and set its value data to 1 as shown below:
4. Now create a new 32-bit DWORD here named DontDisplayLockedUserID. Even if you are running 64-bit Windows, you still need to create a 32-bit DWORD value.
5. Set the DontDisplayLockedUserID value to 3 as shown below:

You are done. Now press Win+L keys together on your keyboard.

Before doing the tweak, the login screen will show your account details when you lock your account:

After doing this tweak, it will be hidden:
