title: Windows environmental variable keeps loading despite removing
body: <p>I don't remember how exactly, but I had set up an environmental variable on Windows. This is not inside the Windows advanced settings -> <em>Environmental Variables</em>.</p>
  
  <p>I have tried to unset it in many ways including, from <code>git-bash</code>:</p>
  
  <pre><code>$ unset DUMMY
  $ env | grep DUMMY
  </code></pre>
  
  <p>This works only for the current session. When I restart or open a new terminal I can still see the variable set. I also tried to unset it from PowerShell as follows:</p>
  
  <pre><code>$ Remove-Item Env:\DUMMY
  </code></pre>
  
  <p>But like the previous technique, this is only for the current session. How can I find where this environmental variable is being loaded?</p>
  
  <p>PS: To clarify, this is an environment variable that I created myself some weeks ago, but I forgot where/how I had set it to stay persistent.</p>
