Windows 10 has a revamped Lock and Login screen that looks awesome with Windows Spotlight’s gorgeous wallpaper images. But it also displays some personal information such as user’s name and email address above the password or PIN box that may concern some people, especially when using your own computer in a public space.
There are settings that you can tweak to ease these concerns, fortunately.
To hide email address from the lock/login screen, go to Settings → Accounts → Sign-in options, and turn on the setting called “Show account details on sign-in screen“.
Then take a look the login screen, you will notice that the email address will no longer show up there as part of the user info.
There are also a couple of more Group Policy settings that you can tie up a little bit more. Open Group Policy Editor, navigate to
Computer Configuration → Windows Settings → Security Settings → Local Policies → Security Options.
Enabling the setting “Interactive Logon: Do not display last user name” removes all information used previously to log into the system. You will need to put in both username and password every time you log in or unlock the computer. Could be tedious but a well-protected method to be used in the public.
Adjusting the setting “Interactive logon: Number of previous logons to cache” lets you increase or decrease the number of previously logged on user accounts to show on the login screen. By default, you can have 10 accounts showing.
As a bonus tip, you can force Ctrl+Alt+Del to be used to start a login process. Simply disable the setting called “Interactive Logo: Do not require CTRL+ALT+DEL“.
