title: npm install extremely slow on Windows
body: <p>This question was asked a lot of times here on Stackoverflow, though no suggestion fixes it for me. What I've tried:</p>
  
  <ul>
  <li>disabled windows security real-time protection and windows defender firewall</li>
  <li>disabled progress bar (take a look at this <a href="https://github.com/npm/npm/issues/11283" rel="nofollow noreferrer">issue</a>)</li>
  <li>reset registry (as this <a href="https://stackoverflow.com/questions/41663198/npm-install-is-extremely-slow">question</a> points)</li>
  <li>performed complete nodeJS and npm uninstall</li>
  <li>yes, network is good (I even tested npm within my neighbour's net: no way)</li>
  </ul>
  
  <p>I'm not sure if the issue affects other commands: npm -v takes nearly 1 second to execute: it's longer than <code>node -v</code>, but perhaps still within normal.</p>
  
  <p>Not a hardware issue: on ubuntu, performance is perfect.</p>
  
  <p>npm version: 6.14.4 <br>
  nodeJS version: 12.16.3</p>
