Add me as a satisfied customer. I had some doubts that this would work for me on an older HP workstation since HP stated there would be no additional Bios updates for the HP Z640.
It didn't exactly work the first time, because I cleared the keys and Windows didn't recognize that secure boot was on after running the update and then enabling secure boot. I had to reset the keys to factory defaults which deleted all the new certs and I had to start over. I then disabled secure boot again, ran the update, enabled secure boot again and had the certs. I did revoke the old certs and copied the SKUSiPolicy.P7b.
All is good.
Thanks a bunch.
