Error message "A recently installed program has disabled the Welcome screen and Fast User Switching" while turning on the Welcome Screen

Symptom

When you attempt to turn on Fast User Switching or Welcome Screen, you may receive a message stating that a program used CSGina.dll ( or any other DLL ginamsi.dll etc ) to disable the Fast User Switching and the Windows Welcome screen features. The exact error message follows:

A recently installed program has disabled the Welcome screen and Fast User Switching. To restore these features, you must uninstall the program. The following file name might help you identify the program that made the change: <DLL filename varies>

Cause

This issue occurs if a third-party GinaDLL value is set in the registry, thus disabing the Microsoft Graphical Identification and Authentication file (Msgina.dll) automatically. CSGINA.DLL is a filter driver of Cisco Systems VPN Dialer program. The filename may vary depending upon the software that you've installed.

Resolution

To resolve the problem and restore the Welcome Screen and Fast User Switching, you need to reset the GinaDLL entry using these steps:

> Click Start, Run and type REGEDIT

> Navigate to the following key:

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon

> Backup the key by exporting to a file.

> In the right pane, right-click GinaDLL, and then click Delete.
(You need to remove the whole value, not just its Value Data)

> Close Registry Editor
