|Identify||Identify-level COM impersonation level that allows objects to query the credentials of the caller. Calls to WMI may fail with this impersonation level.|
|Impersonate||Impersonate-level COM impersonation level that allows objects to use the credentials of the caller. This is the recommended impersonation level for WMI calls.|
