Fix ?Windows Logon Interface Not Loading? Issue

Gina.dll is a Windows file that is used in Windows Operating systems (NT\200\XP) to provide customizable user identification and authentication procedures.

Gina.dll Error

The default Windows logon interface may not appear when you boot your PC after installing a third-party program. If you are using Windows XP computer, you may not be able to use the Welcome Screen or Fast User Switching feature.

When you try to enable Fast User Switching or the Welcome Screen feature via the Control Panel, you may receive the following error message:

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

Note: The <DLL Filename> in the above error message varies and points to the DLL of the third-party program you have installed. For instance, if you have installed Cisco Systems VPN Dialer Program, the <DLL Filename> will be csgina.dll.

Cause of the Error

The above issue occurs when a third-party program replaces the Microsoft Graphical Identification and Authentication file, which is Msgina.dll.

Resolution Steps

To fix the issue and restore the Fast User Switching and Welcome Screen, perform the following steps:

Note: The steps illustrated below require you to edit the registry. Be careful while making any direct changes to the registry because any incorrect registry modification may cause irreparable damage to your system. This is why it is recommended that you make a registry backup before you modify it. This allows you to restore the registry if any complications occur. You can back up the registry manually or use the help of an advanced registry cleaning tool, such as RegServe.

  1. Go to Start and click the Run command.
  2. In the Open box, type regedit and then click OK.
  3. In the left-pane of the Registry Editor window, navigate to the following registry entry:

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

Malware programs, such as viruses may also delete or modify the msgina.dll string-value in the registry and prevent Logon User Interface from loading. This may cause a DLL error message to appear when you start your system. This is why it is imperative that you keep your system safe from malware. We recommend you install robust antimalware tools, such as STOPzilla Antivirus and Spyware Cease, and schedule regular malware scans of your entire system.
