tpm wmi events

TPM WMI events are informational logs generated by the Trusted Platform Module and exposed through Windows Management Instrumentation. On WindowsForum.com, discussions focus on Event ID 1801 and similar TPM WMI events that appear during Microsoft's phased Secure Boot certificate refresh, such as the Windows UEFI CA 2023 update. These events are not signs of compromise or failure but indicate that Windows and OEM firmware are coordinating to apply new certificates safely. Users share experiences with transient "under observation" messages in Event Viewer and seek clarification on whether these logs require action. The tag covers troubleshooting, interpretation of TPM telemetry, and understanding how firmware updates interact with Windows security features.
