I\'m trying to create a utility similar to Microsoft\'s abandoned Super Fast User Switcher (download), which allows fast user switching without going through the Welcome scr
I solved this in XP by calling the undocumented InitiateInteractiveLogon function in the ShellLocalMachine COM object in shgina.dll.
This method, which can only be called by the Local System account, will log a user on to the console. (It cannot log a user on to an RDP session)
The version of the DLL included with Windows 7 (and presumably also Vista) does not contain this method.
