After recent updates, Event Viewer is showing repeated CertificateServicesClient-CertEnrol errors. This is happening across multiple Windows 11 devices. It’s cluttering logs and raising concerns about certificate handling

    Hi,

    This behavior may be linked to changes in certificate auto-enrollment or group policy settings introduced in recent cumulative updates. We recommend reviewing your certificate authority configuration, auto-enrollment policies, and network connectivity to domain controllers, as these can all impact certificate requests.

    If the errors persist and no functional impact is observed, you may consider adjusting logging levels or filtering these events to reduce noise.

    If my answer is useful for you, please vote for it.

    Best regards,

    Quinnie Quoc.
