Summary

  • Microsoft will show Secure Boot certificate status in Windows Security starting April 2026 (notification icons: green/yellow/red).
  • Most 2024 PCs don’t need the new Secure Boot certification, but older machines will need to update it manually via Windows Update.
  • Windows Security shows green/yellow/red: green means you’re good, yellow means manual update, and red means you’re blocked by a vulnerability.

In February, Microsoft announced plans to release new Secure Boot certificates through Windows Update. Fast-forward to now, and the tech giant has offered more information on how this works and rolled out the feature.
