Check the Secure Boot certificates on Windows 11
Secure Boot is one of Windows 11’s quiet security guards — it helps make sure your PC starts with trusted software instead of something sneaky trying to load before Windows does.
In this Bob The Cyber-Guy tutorial, we take a practical look at how to check the Secure Boot certificates on a Windows 11 computer. This is not panic-button territory, but it is useful information for anyone who wants to better understand what their system is showing and why Secure Boot matters.
You’ll see where to look, what the certificate information means in plain English, and why keeping Windows and your PC firmware updated is still one of the smartest security habits around.
Simple, practical, and senior-friendly — because computer security should not require a secret decoder ring.
This is the fastest way and works on all updated Windows 11 systems (April 2026 Windows 11 update or newer).
Steps:
Open Start → Windows Security
Select Device Security
Click Secure Boot
Look at the status badge:
Green checkmark → “Secure Boot is on and all required certificate updates have been applied.”
Your system has the 2023 certificates.
Yellow warning → Your device is still running older certificates; update may be pending.
Red icon → Immediate action needed (BIOS update or certificate issue).
