Microsoft has explained that Windows 11 may restart multiple times during updates. The company says this behavior is expected when deploying the 2023 Secure Boot certificate.
Secure Boot certificate replacement triggers multiple restarts
The 2023 Secure Boot certificate replaces a 2011 certificate that expires in June 2026. Users can check Secure Boot status in Windows Security Center under Device Security. Older devices with outdated firmware may fail to install the new certificate.
The multiple reboots are a normal part of the certificate deployment process. Microsoft's clarification aims to reassure users who experience repeated restarts during the update.
Windows Latest reported the explanation from Microsoft. The company has not confirmed the exact timing of the certificate rollout beyond the 2026-04 Patch Tuesday.
