The Apply the default user logon picture to all users machine setting should be configured correctly. This policy setting allows an administrator to standardize the logon pictures for all users on a system to the default user picture. One application for this policy setting is to standardize the logon pictures to a company logo. If you enable this policy setting, the default user logon picture will display for all users on the system with no customization allowed. If you disable or do not configure this policy setting, users will be able to customize their logon pictures. Fix: (1) GPO: Computer Configuration\Administrative Templates\Control Panel\User Accounts\Apply the default user logon picture to all users (2) KEY: HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\UseDefaultTile
