The Msgina.dll file interacts with the Winlogon service to provide the Welcome screen and the Fast User Switching feature. Third-party software can replace the current Graphical Identification and Authentication data with their own Graphical Identification and Authentication data. The Fast User Switching feature and the Microsoft Welcome screen are not available if you are using a third-party product that replaces the Microsoft Graphical Identification and Authentication file (Msgina.dll).
