Updated redirecting URL in external links+refs and added archive URL. But I don't think this is sufficient evidence for the claims for which it's cited. It states that GINA DLLs are ignored in Vista, but says nothing about Windows 7/8/8.1/10/11. The URL refers to Win32, so we don't know how much of it applies to 64-bit Windows. And there are no sources cited for GINA being used in XP and 2000. As for initial processes e.g. the shell, these are not mentioned on the page. |

GINA is a replaceable [[dynamically linked library]] that is loaded early in the boot process in the context of [[Winlogon]] when the machine is started. It is responsible for handling the [[secure attention key|secure attention sequence]], typically [[Control-Alt-Delete]], and interacting with the user when this sequence is received.

==Overview==
[[File:Xp windows security.png|thumb|250px|right|"Windows Security" dialog in Windows XP: GINA is responsible for bringing up this dialog when [[Ctrl+Alt+Delete]] key combination is pressed]]A default GINA library, MSGINA.DLL, is provided by Microsoft as part of the operating system, and offers the following features:
*Authentication against Windows [[Windows Server ___domain|___domain]] servers with a supplied user name/password combination.
*Displaying of a [[legal notice]] to the user prior to presenting the logon prompt.
*Automatic Logon, allowing for a user name and password to be stored and used in place of an interactive logon prompt. Automatic logon can also be configured to execute only a certain number of times before reverting to interactive logon. In older versions of [[Windows NT]], the password could only be stored in plain text in the registry; support for using the [[Local Security Authority Subsystem Service|Local Security Authority's]] private storage capabilities was introduced in Windows NT 4.0 Workstation Service Pack 3 and Windows NT Server 3.51.
*"Security Options" dialog when the user is logged on, which provides options to shut down, log off, change the password, start the [[Windows Task Manager|Task Manager]], and lock the workstation.
