All my best wishes for 2026.

I Have 2 TPM-WMI related errors, ID 1040 and ID 1801

1040 is logged at 02-01-26 time 11:28:43 and 1801 01-01-26 time 11.33.40
There are no other errors.
I have tried to solve these error, but failed in doing so, lack of knowledge on my side,

System specs are

Mobo Gigabyte Technology Co., Ltd.
Model A520M S2H
Type x64-based PC (Windows 11)
System-SKU Default string
Processor AMD Ryzen 5 5500, 3600 MHz, 6 core('s), 12 processor(s)
BIOS-version/date American Megatrends International, LLC. F19b, 11-07-24
SMBIOS-version 3.3
BIOS-modus UEFI

I have tried to update the bios, but that also failed, Q-Flash does not read the extracted file F20.
(USB plugged in the main usb and it is 32 bits)

Error text ID1040
Pre-attestation health checks confirm a critical component has failed, and the device is not expected to pass attestation.
Please see C:\windows\Logs\MeasuredBoot\0000001088-0000000000.json for detailed information on what checks were made.

Error ID 1801
Secure Boot certificates have been updated but are not yet applied to the device firmware. Review the published guidance to complete the update and ensure full protection. This device signature information is included here.

I have no idea if this situation is a problem and how to solve those errors.
Thanks in advance

These events do not indicate a faulty TPM or a broken Windows installation. What you are seeing is a combination of firmware-level attestation information and Secure Boot certificate lifecycle changes introduced by Microsoft.


Event ID 1040 (TPM-WMI / Measured Boot)​


This event means that Windows performed a Measured Boot health check and determined that the system does not fully meet the latest device attestation requirements.
This does not affect normal operation, performance, or stability.


Measured Boot attestation is primarily used in enterprise scenarios (Device Health Attestation, Intune, BitLocker Network Unlock). On a home Windows 11 system, this event is informational only and can safely be ignored.


The referenced JSON log simply documents which firmware measurements did not match current attestation expectations; it does not imply hardware failure.



Event ID 1801 (Secure Boot certificates not yet applied)​


This event is related to Microsoft’s Secure Boot CA certificate updates (2024–2025).
Windows has successfully updated the certificates at the OS level, but the firmware has not yet imported them.


This is common on systems running:


  • older BIOS versions
  • beta BIOS builds (such as F19b)
  • firmware that does not automatically apply new Secure Boot certificates

Important clarification:


  • Secure Boot is still active
  • the system is not less secure
  • this is a firmware synchronization notice, not an error


BIOS update and Q-Flash behavior​


Q-Flash refusing a BIOS file usually indicates a revision or compatibility mismatch, not a problem with the motherboard.
Gigabyte boards require:


  • the correct BIOS file for the exact board revision
  • FAT32-formatted USB
  • a supported (non-beta, if applicable) BIOS branch

This issue is separate from the TPM events and does not indicate TPM malfunction.



What to do​


If the system is working normally:


  • No action is required
  • These events can be safely ignored on a personal Windows 11 PC

If you want to eliminate the messages:


  • update to the latest stable BIOS for your exact board revision
  • load optimized defaults afterward
  • ensure Secure Boot and fTPM are enabled

Again, this is optional, not mandatory.



Summary​


These TPM-WMI and Secure Boot events are informational firmware/attestation messages, not errors. They do not indicate defective hardware or an unstable system and are common on Windows 11 systems with older or beta firmware.
