The OnScreen Logon Utilities for Windows 2000 / XP have been provided to enable the implementation of Pen and Touchscreen systems without the need for a physical keyboard. Because the default name/password logon options for Windows 2000 / XP required a Ctrl-Alt-Delete keystroke combination, Pen and Touch systems still had to resort to a physical keyboard if a secure logon was required. Now with the OnScreen Keyboard Logon Utility, a secure logon can be accomplished without the need of a physical keyboard.
In addition, the Automatic Logon option has also been incorporated as a convenience within this utility, allowing a fixed user/password combination to start up Windows 2000 / XP without any user interaction required.
There are 2 options available - the original Logon Utilities for Windows NT, and My-T-Soft 2 (for Windows 2000 and Windows XP)
To address changes in Windows 2000 & XP, and to allow customized layouts of the logon keyboard, the My-T-Soft 2 approach enables the use of a My-T-Soft 2 keyboard during the secure logon sequence. The keyboard can be modified with IMG's "Build-A-Board". Advanced notes below refer only to the IMGLOGON.DLL approach - when using the IMGGINA2.DLL (My-T-Soft 2 option), the interface, user shell creation, and all logon capabilities are handled by the default MSGINA.DLL (Microsoft GINA) (or other selected GINA DLL).

Display Domain/User option for Locked Workstation (Security feature)
