title: When does SCCM download updates
body: <p>I'm pretty sure that I know the answer to this but I just want to be sure.</p>
  
  <p>We have SCCM 2012 R2.  Lately I've been receiving complaints from my boss that when deploying updates I am saturating our internet line.</p>
  
  <p>I've configured all the distribution points to not distribute updates during the day via Scheduling and Rate Limits in each distribution point so I can only assume that when I am creating the deployment package for an update that it is then that it is actually downloading the files from Microsoft.  Is this true?</p>
  
  <p>What I need to be able to do is to either proactively or reactively download all updates in off hours ... just occurred to me, is this done through the WUSUS console maybe?</p>
