Microsoft confirms Windows 11 may restart multiple times after updates and your PC isn’t broken, as it’s due to Secure Boot 2023

Microsoft has confirmed that Windows 11 may restart multiple times after updates, specifically due to Secure Boot 2023 certificates. While typical updates only require one reboot, the Secure Boot update process may necessitate additional restarts. The rollout of Secure Boot 2023 certificates began with Windows 11's April 2026 updates. Users can check the Secure Boot status in the Windows Security app to ensure the certificates are updated. Microsoft is committed to addressing Secure Boot certificates on modern PCs, but older machines without updated BIOS/firmware may face challenges with the update process.
