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. Your implementation of this policy depends on your security requirements for displayed logon information. This behavior is the same when the Switch user feature is used. If this policy is disabled, the full name of the last user to log on is displayed, and the user’s logon tile is displayed. The logon screen requests a qualified domain account name (or local user name) and password. Additionally, if the Switch user feature is used, the full name and logon tile are not displayed. If this policy is enabled, the full name of the last user to successfully log on is not displayed on the Secure Desktop, nor is the user’s logon tile displayed. This security policy setting determines whether the name of the last user to log on to the device is displayed on the Secure Desktop. Before Windows 10 version 1703, this policy setting was named Interactive logon:Do not display last user name.

Describes the best practices, location, values, and security considerations for the Interactive logon: Don't display last signed-in security policy setting.
