OEM Readiness for Secure Boot Certificate Updates

Microsoft has been working closely with Original Equipment Manufacturers (OEMs) that build Windows devices to ensure a smooth transition for the upcoming Secure Boot certificate update.

Together, we’ve focused on early planning, validation, and clear communications to help ensure devices remain secure and ready for this change. By partnering closely with OEMs across the industry, we’re building a strong foundation for this transition and reinforcing the security foundation of Windows devices.

As you plan for Secure Boot updates in your organization, check with your OEM for guidance and resources to ensure your devices are ready.
