C:\Windows\System32\Drivers\DDDriver64DCSa.sys
This is a bit of a success story, but also a rant at Dell
For about a year now I have been unable to turn on Win 11 Core Isolations Memory Integrity.
Windows would report I had an out of date driver which needed updating, but did not list any drivers which were the cause ???.
Found out yesterday Microsoft have a Memory integrity system readiness scan tool you can download from here ..

.. hvciscan_amd64.exe
Run it via an elevated Command line, and you will get actual results for any problem drivers/files.
In my case it was one file, which was left behind by Dell when they decided to pull a part of their support software. Idiots.

HVCI incompatible driver scan start...
HVCI: Error 1168 querying "C:\WINDOWS\System32\drivers\dddriver64Dcsa.sys" in the SDB
HVCI: Driver scanning complete
HVCI: scan get result failed.
I had to right click on the file and choose Properties, Security tab, and then go through the process of giving myself rights to delete it.
Once deleted, I could now select Windows Core Isolation Memory Integrity .. Peace of mind at last.
Historically Dell do things like this occasionally, little foobars with their support software not managing itself 100% correctly, overlays of old update extensions to support software for example which dont get uninstalled when the base update software is updated negating the need for the update extension which is still run after the base update and is incompatible .. causing knock on effects for windows and turn into a nightmare of trying to figure out what the hell is going wrong.
Dell, sort your shit out!.
Its pointless me going onto a Dell support site as Dell don't seem to listen, its just other users listening and helping, so Dell Tech guys never get to see any issues they need to solve .. So I may aswell shout out from here as anywhere else.
