The internet is full of misinformation, exaggerated claims, and fear‑based rumors—especially around Windows, Secure Boot, firmware updates, and end‑of‑support timelines. This page separates fact from fiction using clear explanations, real technical details, and verified information.
🔥 Popular Rumors & Myths
Below are some of the most common tech rumors circulating online, along with the real facts behind them.
Myth #1: “Microsoft will use a DBX update to disable Windows 10 on June 24, 2026.”
Reality: This claim is false and technically impossible. The DBX (Secure Boot Revocation List) only blocks compromised bootloaders—not operating systems. Revoking Windows 10’s bootloader would also break Windows 11, Windows Server, Azure cloud systems, and millions of enterprise devices. Microsoft has never used the DBX to disable any version of Windows.
Myth #2: “Secure Boot is going to block older PCs from running Windows 10.”
Reality: Secure Boot does not block Windows 10. It only checks that the bootloader is trusted and not tampered with. Windows 10 continues to boot normally on Secure Boot systems, even after end of support. Secure Boot protects users—it does not disable operating systems.
Learn how Secure Boot actually works.
Myth #3: “The Windows 10 ‘Secure Boot Security’ status means your PC is unsafe.”
Reality: The Windows 10 Device Security page simply reports whether Secure Boot is enabled. It does not mean your PC is unsafe if the status shows “Secure Boot Security.” It’s just an informational label, not a warning.
What the Secure Boot Security status really means.
