Microsoft has resolved an issue in Windows 11 version 24H2 that generated false CertificateServicesClient (CertEnroll) error messages. The glitch appeared after the installation of the July preview update KB5062660 and persisted through all subsequent releases, including the August security package.
At the time, the company acknowledged the bug and advised users to disregard the warnings logged in Event Viewer, which claimed that the Microsoft Pluton Cryptographic Provider had failed to load. The spurious error appeared at every system restart but had no impact on Windows components or system processes. Microsoft explained that the root cause was linked to a feature still under development and not yet fully integrated into the operating system.
On August 29, the corporation updated the Windows Release Health dashboard, confirming that the problem had been fixed. The patch has already begun rolling out and will be deployed gradually over the next four weeks. It will be automatically enabled on Home, Pro, and enterprise editions of Windows 11 managed through Microsoft tools. To apply the fix, users need only update their systems to KB5064081. Once phased deployment is complete, all future cumulative updates will include the correction by default.
This is not the first time in recent months that Windows has displayed erroneous warnings. In June, Microsoft admitted to a bug that triggered false firewall configuration errors following a preview update. In April, it addressed a flaw that produced error 0x80070643 during the installation of Windows Recovery Environment (WinRE) updates—even though the updates themselves completed successfully. That same month, the company also corrected misleading BitLocker disk encryption notifications on Windows 10 and 11 devices.
Thus, the July incident with CertEnroll joins a series of cases in which users were confronted with alarming but ultimately harmless messages. Microsoft has now confirmed that the latest system patch will definitively bring this particular bug to a close.
