Your Windows PC’s security foundation could expire in 8 weeks — Here’s how to check if you’re eligible for a new Secure Boot certificate

AI-summarised brief · reviewed before publication

Microsoft's implementation of Secure Boot on Windows PCs in 2011 has led to a critical issue: countless Secure Boot certificates are set to expire in June 2026. This marks the first time the certificates have reached a cutoff date, prompting Microsoft and OEMs to transition to new certificates. Users who fail to update their certificates may require manual action to maintain their PC's security.

💡 Why It Matters

  • · The Secure Boot certificate expiration threatens to undermine the security foundation of millions of Windows PCs.
  • · As a result, a significant number of users will be forced to take manual action to ensure their devices remain secure, highlighting the importance of timely software updates in maintaining system integrity.
