When you install Microsoft System Center 2012 Configuration Manager client, you may find that many warning messages for PolicyAgentInstanceProvider are logged in the Application log. Those messages resemble the following:
This problem occurs because Configuration Manager is not included in the Windows Management Instrumentation (WMI) exclusion list of providers that can run under the local system account at the time of installation.
These messages are expected during the installation of Configuration Manager Client and can be safely ignored. PolicyAgentInstanceProvider is registered as safe with WMI during Setup, so the warning messages should stop being logged as soon as the Setup program is finished.
