HVCI incompatible driver scan start...
HVCI: Driver scanning complete
HVCI incompatible driver scan passed!
I'm not sure if it would have found the "virtual" Driver for Dell's SupportAssist software, dellinstrumentation.inf [dellinstrumentation.sys] which HST222 mentioned earlier from when I ran driverquery /v.
I think I'm now reading on this blogpost that Memory Integrity switches back OFF after reboot. Not sure yet if I have that problem or not, but at least I am not seeing the "Incompatible Drivers" error (and blank page for a link that I think said "more info" but with NO DRIVERS LISTED) as I was seeing earlier when I tried to switch on Memory Integrity.
