I'm developing a kernel driver for Windows and recently MS deprecated the procedure to sign drivers, see

I tried contacting them 2 months ago and they claimed that submitting drivers is still the same for attestation (which I use), as documented here

However, after following the instructions, my driver fails to load with error 0x800B010C A certificate was explicitly revoked by its issuer Any idea why? Seems MS closed the dev support chat and they no longer answer my emails.


What I have tried:

purchased EV certificate, uploaded it to the MS portal, submitted for attestation (see above) and tried loading the driver signed by MS.
