MicrosoftThis is great if you have several dozen servers or more and lots of time to read complex detailed instructions and many IT people to do it. But that's not me. I have six WIN 2022 servers in six separate locations some as much as 90 miles away, and 106 computers spread out across those locations, plus copiers, printers, security cameras, security doors and systems. Large lobby media display setups and public computers and kiosks ... and I am the only IT person in the entire organization. I need to have a simple set of step by step instructions that I can complete once on each server and then go on with all of the other things I have to do. Being out in a very rural area where IT people are few and far between and the sites are spread out is very different than a big corporate office. Where there are lots of staff and most things are right close by. I do not have the time or resources to set up and monitor servers on a daily basis. It's on early Sunday mornings when I do the updates and upgrades because that's the only time available to me.
GDennis Updating secure boot certificates is not a simple topic, that's why there are no simple guides for it. There's a lot that can go wrong, which can cause your server to no longer boot.
Having said that, a simple way of updating the secure boot certificate is to follow Step 4, Option 1, and set the AvailableUpdates key to 0x5944. Reboot it a couple of times and the key should finally reach 0x4000, when all updates are applied.
I strongly recommend taking this as the key information and re-read the guide again to really understand how to understand the process, what to prepare and how to diagnose issues.
Hi Daniel, thanks for the update, and the information. Personally I believe if secure boot is that complex and dangerous then simply turning off secure boot off sounds like the best route. Things simply do not need to be that complex, in the 40 years I have worked in IT, keeping it short and simple is normally the best. Also, Copilot gave me different information than what this indicates and what was in the article (yes I know AI is often wrong). It's a shame that we live in a world where nothing is trusted. Sometimes I long for the days of green screens on an IBM mainframe writing COBOL and assembler and not having to worry about some evil character attacking the firmware I wrote myself. Sigh .... guess I'm showing my age.
Just to clarify a few points: Secure Boot itself isn't the problem, and it's not inherently complex. What is complex is the one-time certificate rotation because Microsoft is revoking old bootloaders. Turning Secure Boot off doesn’t simplify anything. It just removes protection from a class of attacks that now target exactly these outdated bootloaders. You have the freedom to disable secure boot entirely if you prefer, but I would strongly advise against it.
