This article provides guidance for Dell PowerEdge servers requiring remediation for the Microsoft Secure Boot certificate expiration (June 2026). It applies to UEFI-based systems with Secure Boot enabled and older Secure Boot certificates affected by the Microsoft Secure Boot certificate expiration (June 2026). The operating system primarily manages Secure Boot certificate updates, and customers should ensure they update their systems using supported Microsoft update mechanisms. It applies to Windows Server operating systems affected by this change, as defined by Microsoft, running on physical systems with customer-managed firmware and Secure Boot configuration. It does not apply to cloud platforms or appliances where the provider manages firmware and Secure Boot keys, such as Microsoft Azure, AX, or APEX-Managed Cloud. Systems already running BIOS versions that include the updated Secure Boot certificates may not require this procedure.
