Thanks Oney:)). I really want to dig out something about debug registers.
So I have to check some flags in CR4. A normal driver should not do this.

done my share of putzing with CR0 over the years, but mostly in VxD
drivers.It’s not a matter of morals, anyway, despite the way it may have
sounded. I just can’t think of anything useful to do with the value of
CR4 unless you’re trying to write your own virtual memory system from
the ground up. Or writing a debugger.We never got an answer to the “why”, though. So maybe he found another
way.–
