title: listen EACCES: permission denied in windows
body: <p>Everything was worked fine before today evening after i uninstalled vscode and installed again I'm facing this issue while try to run <code>npm run app</code> i  have no clue how to fix this i tried to run vs code and command prompt or bash using run as administrator but no luck, i see lot of fixes out there for this issue but most of them are for mac they fixed it using <code>sudo</code> but i don't see any good fix for windows it would be appreciated much if anyone will help me fix this </p>
  
  <pre><code>//this issue this my server code 
  const express = require("express");
  const app = express()
  const port = process.env || 8080
  
  app.get("/", (req, res) =&gt; {
    res.send("Hello");
  });
  
  
  
  app.listen(port,()=&gt;{
    console.log("running on 8080")
  })
  </code></pre>
  
  <p>and this is the complete error</p>
  
  <pre><code>events.js:187
        throw er; // Unhandled 'error' event
