In the Secure Boot status report in Intune, what is the column Confidence level for? Most of my systems show "Under Observation - More Data Needed" for that column. My Certificate status column shows "Up to date" for all the same systems. I thought I was done, is there more I need to do?

Using Intune CSP - the majority of our devices, including ones with updated firmware, are still in the "Under observation" confidence level bucket, according to Autopatch Secure Boot report.
We haven't seen it changing with latest CUs.
should we now push using the AvailableUpdare=0x5944 before June? - Claude_Boucher_OEMBrass Contributor
Dear all,

I hope it could be helpfull.

If we are using VMWare vSphere and not using Secure Boot and using legacy BIOS, this cause issues after June 2026. Also, how do we get the server setup like this compliant?

So we're using intune/autopilot for our systems. We've seen a small percentage of our systems have blue screen errors during our rollout of the CA2023 update with intune. The errors we've observed are:
7_0_800000001_80000001_SecureBoot_SecureBoot_7_6_ccfc...
7_2_800000001_80000001_KEK_KEK_7_7_63af...
Any ideas why these systems got messed up? Firmware was up-to-date on them. Basically disabling bitlocker and waiting for our bitlocker policy to re-enable it worked on these systems.

we are using Intune --> Autopilot to deploy our computers
If you don’t update and the certificate expires. When a device enrolls will the secure boot process actually be enabled or will it fail to bind to bitlocker and take that with it in one or more policies

How about MacBooks running Windows in Bootcamp/natively?

A comment was made regarding bootable media in regards to the secure boot certificates. We have several USB sticks and PEs used to build systems. If the certificates are expired in the boot media / PE, will those stop working completely in June? Or only when the old certificates are revoked?
Thank you!- IvanCardim
Microsoft
Expiration alone won't impact existing boot media that is working today - they'll only stop working when the 2011 certs are explicitly revoked via a DBX update.

1. A lot of our w365 cloud PCs are showing not upto date and when I applied tge policy it moved to in progress and showing event id 1795. I can see an article which says Microsoft is working on fixing this. How can I make sure if my issue is covered under this.
2. After June how can I update these certificates?
