Windows service showing a GUI when no user is logged in
问题 Is it possible to a display dialog window from a windows service over the logon screen of Windows 7 (when no user is logged in yet) ? I found this article explaining how to display a window on a logged in user desktop but how to do it when there is no user logged in ? I was thinking about trying to automatically log in a user then display the window on his desktop but is it possible to display it directly over the logon screen ? 回答1: GINA was replaced by Windows Vista Credential Provider.
