I don't know, I don't write Windows drivers.

It's called driver filters as far as I know. 

I think the primary problem is abuse, and the fact that it is too easy
to insert one maliciously.

Now we have copy protection systems using them, and not only do they
hurt performance, but they open up ring zero, and disable hardware on
some systems.

I don't see Microsoft closing this up, because a lot of games are now
installing viral driver programs on Windows for copy protection.
