Windows' original Secure Boot certificates expire in June—here's what you (may) need to do

Microsoft has warned that the original Secure Boot certificates used by Windows PCs will expire in June and October of this year. These certificates are crucial for verifying bootloaders to ensure that unverified software can’t be loaded at startup. PCs that do not update to the new certificates before the expiration date may face issues booting new operating systems and installing security patches. Microsoft and major PC manufacturers have been preparing for this transition, and most systems should update seamlessly through Windows Update. Users can check if their PCs have the new certificates using a PowerShell command. Microsoft encourages users who need help with the update to use its customer support services.
