We have Windows 10, Windows Server 2016, Windows Server 2019 in closed network and patching by WSUS.
Refer to information, I understanding that we need to renew the new certificate before Jun 2026.
However, I am not fully understanding how to update the new certificate and how to verify the new certificate had been imported. Would you help?

Important: All Secure Boot registry keys are under these two paths: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecureBoot HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecureBoot\Servicing
The main bit to check is the UEFICA2023Status under Servicing that matches Updated.
