Starting this month, Windows devices will begin displaying a visual cue for one of computing’s less-visible but critical safeguards: Secure Boot. A fresh badge in the Windows Security app signals whether a PC’s boot-level security is current, pending an update, or at risk—marking the first time users can see this status without digging into firmware settings.
The change arrives as Microsoft replaces certificates originally issued in 2011 that are set to expire in late June. The new system uses three distinct indicators: a green check for devices already updated, a yellow caution for those waiting or blocked by hardware limits, and a red stop that could appear once older certificates fade out. Most modern PCs—especially those from 2024 and later—should receive the update automatically via Windows Update; older machines may require firmware assistance from manufacturers.
Users will see the same status reflected in the system tray icon, ensuring warnings remain visible even when the app is closed. While dismissing the yellow or red indicators is technically possible, Microsoft advises against it, as devices without updated certificates risk boot-level vulnerabilities and future compatibility issues with Windows security patches.
A gradual rollout means newer hardware is already covered, but older systems may need manufacturer guidance to ensure compliance before June. No immediate action is required for the vast majority of users whose machines will update automatically, though those encountering blocks or warnings can seek support at a designated assistance page.
