Can I change the window lock screen “reset password” application?

Posted on

QUESTION :

If you use Forefront Identity Manager (FIM) Self Service Password Reset, there is a reset password link on your windows 7 lock screen that opens the FIM password reset application:

lockscreen with fim password reset

Is it possible to edit this link, so that it opens a self developed application?

ANSWER :

Yes, it is possible.

It is also not incredibly easy to get to work reliably. This is partially by design, because by altering the Windows Logon process you could also lower or bypass security.

In short:

Windows 2000/ NT/ XP
Replace MSGINA.DLL in the registry with a custom DLL and update the registry.

Windows NT 6.0+ (Vista+)
You need to create a custom Credential Provider.


If you research this further you will see there are many examples and tutorials. Neither route is exceptionally easy.
