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.
