A week or so ago Microsoft has released Update1606 for System Center current branch.
The 1606 release notes can be found on Microsoft Enterprise Mobility and Security Blog

You will get The command(s) completed successfully.
Now go to \Administration\Overview\Cloud Services\Updates and Servicing node in SCCM console, then run Check for updates.

The SMS_DMP_DOWNLOADER component will start downloading a large file and we can see download of a large file in dmpdownloader.log (<Install_DIR>\Microsoft Configuration Manager\Logs\);
