title: Change default python version for command prompt
body: <p>On my machine I have python3.4 and a recently downloaded python3.6 installed, I would like to set python3.6 as my default python used in command prompt.</p>
  
  <p>I have removed the python34 path variable but my when I access python through the command prompt it still defaults to opening python3.4. I saw <a href="https://stackoverflow.com/questions/24814724/python-how-to-access-3-3-if-3-4-is-the-default">this question</a> about access the non default python but that was for specific files.</p>

  <p><strong>Since posting the question:</strong> </p>
  
  <p>I have also removed python34 from the system path variables.</p>
  
  <p>Typing <code>where python</code> in command prompt returns this:</p>
  
  <pre><code>C:\&gt;where python
  C:\Python34\python.exe
  C:\Python36\python.exe
  </code></pre>
  
  <p>Typing <code>echo %PATH%</code> returns</p>
