I have successfully written some WDF drivers for our proprietary hardware for Windows 10.
Our “normal” software engineers are now writing their user space applications using the drivers with testsigning on.
I see to sign the drivers for release I need to purchase an EV certificate (no problem as we are a legitimate and fairly large company).
I would like to attest sign the drivers and not use HLK.
Is this still possible as it appears sysdev is no more?
