Secure Boot helps ensure that only trusted software runs during the boot sequence. It uses cryptographic keys, known as certificate authorities (CAs), to validate that firmware modules come from a trusted source. After 15 years, the Secure Boot certificates that are part of many Windows systems will start expiring in June 2026. These certificates were originally issued in 2011. Many Windows PCs manufactured since 2024 already have updated (2023) certificates. For the remaining devices, we recommend that you start monitoring the progress of certificate updates today as well as prepare for and install new certificates on devices that aren’t automatically getting them through Windows updates. An initial set of tools and guidance is now available to support you in this effort. When will this happen:While Microsoft will deliver the new 2023 Secure Boot certificates through Windows monthly upd
