HP Recommended
Product: HP ProBook 440 G5 Base Model Notebook PC

Per HP document ish_13070353-13070429-16 ("HP Business PCs – Prepare for new Windows Secure Boot certificates"), HP provides a manual update solution for Commercial PCs outside of service life. I request this solution for my device, which meets the stated requirements:
• Product: HP ProBook 440 G5, baseboard 837D
• BIOS: Q85 Ver. 01.31.00 Rev.A (latest published; released 2025-02-11)
• OS: Windows 10 Enterprise 22H2, enrolled in the Extended Security Updates (ESU) program
• Hardware: meets Windows 11 system requirements (8th-gen Intel Core, TPM 2.0)
• Secure Boot: enabled and healthy
Current certificate state: the Windows UEFI CA 2023 is already applied to the UEFI DB and the boot manager is 2023-signed. The remaining updates — KEK 2023, Microsoft UEFI CA 2023 (3P), and Option ROM UEFI CA 2023 — are blocked by Windows servicing with Event ID 1802, SkipReason KI_7 (known HP firmware issue per Microsoft KB5083344), BucketConfidenceLevel "Temporarily Paused". Since the 450 G5 is not on the supported-platforms BIOS list, no firmware update will lift this block, so the manual EOSL process is the applicable path.
Please advise the procedure and provide the necessary update packages.
