I am aware that this had been asked MANY times, but i’ve spent a good amount of time looking at all of them I could find, and I haven’t gotten a good answer. I do understand the concept of an NMI and I am aware that I cannot intercept the call. I was just wondering if I were to develop a GINA application, could I respond to ALL the hooks that the operating system calls so that I can just ignore them? Are there some hooks that get executed regardless of my GINA implementation? I have run across many little utilities that will tweak the registry for me, but I want to handle it all in code without changing the registry.
PS, I DO NOT want to write my own keyboard driver nor do I want to hack around in BIOS land…
Also, I have read that Win 7 does not use GINA. Am I wrong? If not, what Windows component do I need to implement/replace in order to do the same thing?
GINA was killed by Vista. So you are right that it’s not present in Windows 7. The replacement functionality is credential providers. They certainly don’t allow you to intercept SAS.
