Does a GINA implementaion allow me to ignore SAS kernel calls?

Question

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?

Answer 1

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.
