PCWorld reports that Microsoft has confirmed Secure Boot certificate update failures on certain PCs, particularly affecting HP models after certificates expired on June 24th. While PCs continue operating normally, outdated certificates gradually reduce security protection against new threats over time for Windows 10/11 users.
