Then there's a patched version that does not cause the bluescreen. Great! Except that you can no longer install unsigned drivers on Windows 10 by putting your machine into test mode.

Patching out the signing check itself may not be too difficult... and if the file the signing check is in is also signed and verified by something else, then patch that... it's patches all the way down. I remember doing this with Vista a long time ago. When the signing check fails it fails with a very distinctive error code/message, so I searched for that in all system files and went "down the rabbit hole" of patching out a few checks. I don't remember the details but there was less than a dozen bytes that needed to be changed. Previous cracking experience certainly helps. ;-)

Yeah but I want to distribute the result to users and patching driver signing checks out of their Windows installs is not an option. You are right though.

Instead of patching out one approach could be to add your own certificate to Microsoft's to allow yourself to sign your own drivers. but not nefarious actors.
