title: conda is not recognized as an internal or external command, operable program or batch file
body: <p>I was updating pandas (on windows 7) using:</p>
  
  <pre><code>conda update pandas
  </code></pre>
  
  <p>accidentally I closed the command window while updating.
  Now I can't start spyder and if I type conda in the command window I get:</p>
  
  <pre><code>"conda is not recognized as an internal or external command operable program or batch file"
  </code></pre>
  
  <p>if I type spyder --show=console I get</p>
  
  <pre><code>from PyQt5.Qtwidgets import * 
  importerror: DLL load failed: The specific module could not be found
  </code></pre>
  
  <p>Any idea how to solve this?</p>
