"This policy enables Corporate Error Reporting, which allows you to send all error reports to a file server on your local network.

If you ENABLE this policy no reports are sent to Microsoft.  All error reports are sent to the specified file path, which may be a UNC or drive letter.  You may use the Corporate Error Reporting tool (CER) to view the reports and optionally batch upload them to Microsoft.

If you DISABLE or DO NOT CONFIGURE this policy, error reports are sent to Microsoft, unless reporting is disabled."
