Microsoft Confirms Harmless Bug in Windows 11 Update That Generates Misleading Error Logs

Microsoft has alerted Windows 11 users to a new false notification that appears after installing the July 2025 preview update and subsequent 24H2 releases. The issue is linked to the CertificateServicesClient (CertEnroll) component and is recorded in the system log as a failure, though it has no impact on the platform’s functionality.

In recent months, the company has encountered similar cases where updates triggered inaccurate alerts about non-existent issues. In June 2025, for example, some users received firewall modification warnings after restarting their PCs, even though protection remained fully operational. In April, Microsoft fixed a bug that displayed error code 0x80070643 following Windows Recovery Environment (WinRE) updates, despite no actual fault, and also addressed a misleading system report that generated BitLocker encryption alerts. The latter issue affected only managed enterprise configurations with policies requiring cryptographic verification of system and removable drives.

Now, another entry has been added to the list of notifications that require no action. In Event Viewer, it appears as an error with ID 57, stating that the Microsoft Pluton Cryptographic Provider module failed to load due to an initialization error. After installing the July KB5062660 update or newer releases—including the August security update—Event Viewer also records a CertEnroll-related event at each system startup.

According to Microsoft, the root cause lies in functionality still under development and not yet integrated into the system. Although the log entry appears consistently, it does not indicate any malfunction in active Windows components and requires no administrative intervention. Engineers plan to eliminate the issue as the new feature’s integration progresses; until then, users are advised to simply disregard the message.
