title: Can't find config.xml anywhere within Jenkins folder
body: <p>I have downloaded and installed Tomcat servlet on my Windows 8...</p>
  
  <p>Inside which many application's <code>.war</code> files are present. Also Jenkins. I was able to start it and create jobs and plugins through it. But I gave a wrong credentials for <em>Advanced -> plugin -> HTTP Proxy</em> while installing Maven. Maybe this is what is blocking me to login and gives message: Admin Is Missing the Overall/Read Permission. </p>
  
  <p>I searched in Jenkins and many other sites; hey had mentioned to follow these steps...</p>
  
  <ol>
  <li>Stop Jenkins (the easiest way to do this is to kill the servlet container.)</li>
  <li>Go to <code>$JENKINS_HOME</code> in the file system and find config.xml file.</li>
  <li>Open this file in the editor.</li>
  <li>Look for the <code>&lt;useSecurity&gt;true&lt;/useSecurity&gt;</code> element in this file and replace <code>true</code> with <code>false</code></li>
  <li>Remove the elements <code>authorizationStrategy</code> and <code>securityRealm</code>.</li>
  <li>Start Jenkins</li>
  </ol>
  
  <p>But I searched everywhere to find the <code>config.xml</code> on Windows, but I can't find it. Where it is?</p>
