Event details
Has MS encountered any known issues regarding certain 3rd party components and the certificate expiration? We've been attempting to work specifically with NVIDIA to confirm if changes are required directly on any GPUs in support of this expiration, but I would like to hear MS's position on the potential for issues on 3rd party components as it pertains to the expiration of the 3rd party ROM cert. Still waiting for official feedback from NVIDIA, but this Reddit article is what piqued my interest.

There are no plans to revoke the Option ROM cert. So old option ROMs that have been signed with the old option rom cert before 2023 will keep functioning. Same for the UEFI CA certs. If you got something custom-signed through Microsoft with the old 2011 cert (or someone else had, thinking of for example Vent oy multi-usb-boot), it won't stop working.
