title: Update Windows 10 from 1507 to 1607
body: <p>I am in a bit of a pickle.</p>
  
  <p>I have a development machine, imaged at <strong>1507</strong> version of windows,
  I do need to update it to <strong>1607</strong> Anniversary Update to replicate a bug our software has.</p>
  
  <p>The caveat is version <strong>1703</strong> Creators is already out.</p>
  
  <p>How can I update my system from <strong>1507</strong> to a specific 1607 version of windows 10?
  What I've considered</p>
  
  <ol>
  <li><strong>Windows update</strong> - it is not working, I think windows build <strong>1507</strong> is already too old and is excluded from WU.</li>
  <li><strong>Windows Update Assistant</strong> - is trying to bump me all the way to <strong>1703</strong> ( Creators Edition ) which is not what I need.</li>
  <li><strong>MediaCreationTool</strong> - I have found a media creation tool targeted specifically for <strong>1607</strong> build from a 3rd party website, but I want to upgrade the system, not re-install the whole windows. And my understanding is this tool will re-install not update the image.</li>
  </ol>
  
  <p>What I think would work for me I think is the <strong>Windows 10 Upgrade Assistant</strong> set to update <strong>1607</strong> specifically, but I can't seem to find that option / download. I only found the assistant version that will take you directly to the latest greatest <strong>1703</strong> ( Creators Windows 10 build )</p>
  
  <p>Any help is appreciated,
  Maciej</p>
