Microsoft has started rolling out new Secure Boot certificates through monthly Windows updates to replace the original 2011 certificates that will expire in late June 2026. These certificates are crucial for ensuring that only trusted bootloaders can load on UEFI firmware, preventing malicious software like rootkits from executing during system startup. The update process involves firmware updates across millions of device configurations from various hardware manufacturers and OEMs. Devices that do not receive the updated certificates will enter a 'degraded security state' with limited boot-level protections. Microsoft advises customers to upgrade to Windows 11, as unsupported versions like Windows 10 will not receive the new certificates.
