- The update resolves an issue that affects the desired state configuration. It resets the previously configured options. This happens if metaconfig.mof is missing.

- The update addresses an issue with the Simple Certificate Enrollment Protocol (SCEP) certificate. The system incorrectly reports some SCEP certificate installations as failed. Instead, the system should report them as pending.
