Expiring secure boot certificate
I have two Inspiron laptops that are out of warranty. I have just read an article in ZDNET concerning the Microsoft Secure Boot certificates from 2011 to expire in June 2026. (https://www.zdnet.com/article/secure-boot-certificate-updates-2026/?utm_source=iterable&utm_medium=email&utm_campaign=techtoday)
Running the command to check if the new certificate has already been installed, both laptops returned 'false'. What do I need to do to get the updated certificates?

Check the model numbers at the link below. Almost anything more than about five years old won't be receiving an update.

Thankyou poster. I thought I was good on my Windows 10 machine but not according to the command in your zdnet link. ejn63, is there a catalog version of the Certificate file ?
