I am trying to create a button on windows (win xp or win 7 and onwards) which can open up a form.

I am able to do that by overriding Utilman.exe by owning it and replacing it with my custom exe renamed as Utilman.exe, but that will suppress the existing features provided by the operating system.

I have looked upon creating custom GINA but not sure if I can achieve the same with it.

If there is any sample or pointers available please provide.

Problem: On windows logon screen I need to provide a button which can invoke a form (with the machine still locked), something like in the below image:

  • XP used GINA. Vista introduced a new credentials API that replaced GINA. You need to pick XP or Vista and concentrate on one at a time. It's no good to ask about both in one question. – David Heffernan Aug 11 '15 at 10:46
  • @DavidHeffernan is it possible with winlogon and credentials api on Vista and onwards ? can you please provide some pointers on this ? – Prashant Aug 11 '15 at 10:49
  • I'm not sure whether or not it is supported with credentials API. What I think some people do (e.g. hardware manufacturers) is run a local system service and hack their way into the lock screen UI from there. Why do you want to do this anyway? – David Heffernan Aug 11 '15 at 11:00
  • Windows 8 and above offers limited support to customize the lock screen. See [Lock screen overview (Windows Runtime apps)](https://msdn.microsoft.com/en-us/library/windows/apps/hh779720.aspx) to get details, on what can (and what cannot) be customized. – IInspectable Aug 11 '15 at 11:24
