title: Error "Unable to open Jupyter Notebook: Port 8888 is already in use"
body: <p>I am getting following error when I run Jupyter Notebook:</p>
  
  <pre><code>(base) C:\Users\ramne&gt;jupyter notebook
  [I 01:19:00.648 NotebookApp] The port 8888 is already in use, trying another port.
  </code></pre>
  
  <p>And when I do netstat -ano | find Str "8888" , I get the following:</p>
  
  <pre><code>C:\Users\ramne&gt;netstat -ano | findStr "8888"
  TCP    127.0.0.1:8888         0.0.0.0:0              LISTENING       16024
  TCP    [::1]:8888             [::]:0                 LISTENING       16024
  </code></pre>
  
  <p>I don't know what the default connection of port 8888 is or what its behavior should be like. How do I fix this error so I can open Jupyter Notebook?</p>
