title: How do I remove a URL from the indexes where pip searches for packages?
body: <p>I am working on a Windows system.
  Python version 3.7,
  pip version 20.3.3</p>
  <p>There was a URL being used in my org for certain packages but now it is inactive.
  But every time I try to pip install a new package now, apart from pypi.com, it also searches in the old inactive url.</p>
  <p><em>Looking in indexes: <a href="https://pypi.org/simple" rel="nofollow noreferrer">https://pypi.org/simple</a>, <strong>http://org_dev:xxxx@xx.xxx.xxx.xxx:xxxx/simple</strong></em></p>
  <p>How do I get rid of it so that pip no longer searches there?</p>
