How can I harden my GINA against modification or simple by-pass?

Problem is that there is a registry entry change. I need something that checks this is correct, and validates my GINA, preferably before it loads.

This is what I wanted a driver for (I'm guessing I can do this from there).

Any resources on this would be greatly appreciated.

My GINA is a straight-forward DLL that forwards 99% of the functions.

Best regards,
