title: jupyter notebook not recognized in fresh miniconda3 instalation
body: <p>I installed fresh miniconda3, from here: <a href="https://conda.io/en/latest/miniconda.html" rel="nofollow noreferrer">https://conda.io/en/latest/miniconda.html</a></p>
  
  <p>when opening anaconda prompt, python works correctly, but <code>jupyter notebook</code> gives the following error:</p>
  
  <pre><code>'jupyter' is not recognized as an internal or external command, operable program or batch file.
  
   where conda
  </code></pre>
  
  <p>show:</p>
  
  <pre><code>C:\ProgramData\Miniconda3\Library\bin\conda.bat
  C:\ProgramData\Miniconda3\Scripts\conda.exe
  </code></pre>
  
  <p>All the answers I found talk about PATH.
  but, I don't see <code>jupyter.exe</code> at all.
  In the past, miniconda installation came with jupyter notebook.
  Was it changed ? do I need to install it separately ?</p>
  
  <pre><code>conda list
  </code></pre>
  
  <p>outputs:</p>
