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
Windows Secure Boot certificates are set to expire in June 2026, marking the first time since the feature’s introduction in 2011 that users will face this security infrastructure milestone. The certificates, which form a critical component of PC security, have been in use for 15 years without reaching an expiration date until now.
Microsoft and original equipment manufacturers (OEMs) are coordinating a significant effort to manage the transition to new certificates. This proactive approach aims to ensure that the renewal process is as seamless as possible for the millions of Windows users worldwide.
For most users, no action will be required when the deadline arrives. The renewal process has been designed to be automatic or transparent for the majority of Windows PC users. However, a minority of users may need to take specific steps to ensure their systems continue to function properly with the updated certificates.
The article indicates that additional information and guidance will be provided for those users who are affected and need to take manual action. This represents an important moment for Windows security infrastructure, as it demonstrates Microsoft’s commitment to maintaining the integrity of Secure Boot even as technical requirements evolve over time.
