Describes the best practices, location, values, and security considerations for the Interactive logon: Don't display username at sign-in security policy setting.
A new policy setting has been introduced in Windows 10 starting with Windows 10 version 1703. This security policy setting determines whether the username is displayed during sign in. This setting only affects the Other user tile.
If the policy is enabled and a user signs in as Other user, the full name of the user is not displayed during sign-in. In the same context, if users type their email address and password at the sign in screen and press Enter, the displayed text “Other user” remains unchanged, and is no longer replaced by the user’s first and last name, as in previous versions of Windows 10. Additionally,if users enter their domain user name and password and click Submit, their full name is not shown until the Start screen displays.
If the policy is disabled and a user signs in as Other user, the “Other user” text is replaced by the user’s first and last name during sign-in.
- Not defined
Your implementation of this policy depends on your security requirements for displayed logon information. If you have devices that store sensitive data, with monitors displayed in unsecured locations, or if you have devices with sensitive data that are remotely accessed, revealing logged on user’s full names or domain account names might contradict your overall security policy.

None. Changes to this policy become effective without a device restart when they are saved locally or distributed through Group Policy.
Policy conflict considerations
This policy setting can be configured by using the Group Policy Management Console (GPMC) to be distributed through Group Policy Objects (GPOs). If this policy is not contained in a distributed GPO, this policy can be configured on the local computer by using the Local Security Policy snap-in.
This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.
An attacker with access to the console (for example, someone with physical access or someone who can connect to the device through Remote Desktop Session Host) could view the name of the last user who logged on. The attacker could then try to guess the password, use a dictionary, or use a brute-force attack to try to log on.
Enable the Interactive logon: Don't display user name at sign-in setting.
Users must always type their usernames and passwords when they log on locally or to the domain. The logon tiles of all logged on users are not displayed.
