title: Unable to update npm from 6.14.8 to 7.3; deleting npm.cmd, npx.cmd, and npm leads to more errors
body: <p>I've been attempting to update my npm globally using the <code>npm install -g npm</code> command in Git Bash to keep it current with Angular 11 and Node.js version 15.5.0. I receive the following error:</p>
  <pre><code>npm ERR! code EEXIST
  npm ERR! path C:\Program Files\nodejs\npm.cmd
  npm ERR! Refusing to delete C:\Program Files\nodejs\npm.cmd: is outside C:\Program Files\nodejs\node_modules\npm and not a link
  npm ERR! File exists: C:\Program Files\nodejs\npm.cmd
  npm ERR! Remove the existing file and try again, or run npm
  npm ERR! with --force to overwrite files recklessly.
  </code></pre>
  <p>I deleted the file from <code>nodejs</code> and attempted to install again, but received another error about the <code>npx.cmd</code>. I deleted that file, attempt installation, and received an error about the npm file.</p>
  <pre><code>npm ERR! code EEXIST
  npm ERR! path C:\Program Files\nodejs\npx.cmd
  npm ERR! Refusing to delete C:\Program Files\nodejs\npx.cmd: is outside C:\Program Files\nodejs\node_modules\npm and not a link
  npm ERR! File exists: C:\Program Files\nodejs\npx.cmd
  npm ERR! Remove the existing file and try again, or run npm
  npm ERR! with --force to overwrite files recklessly.
  </code></pre>
  <pre><code>npm ERR! code EEXIST
  npm ERR! path C:\Program Files\nodejs\npm

  </code></pre>
  <p>After deleting them and attempting to install <code>npm</code> again, Git Bash no longer finds npm. The installation never starts.</p>
  <pre><code>bash: /c/Program Files/nodejs/npm: No such file or directory
  </code></pre>
  <p>I tried to delete the npm file from my roaming folder in <code>AppData</code>, but received the following error:</p>
  <pre><code>npm ERR! code ENOENT
  npm ERR! syscall lstat
  npm ERR! path C:\Users\Yoga 2 Mitchell\AppData\Roaming\npm
  npm ERR! errno -4058
  npm ERR! enoent ENOENT: no such file or directory, lstat 'C:\Users\Yoga 2 Mitchell\AppData\Roaming\npm'
  npm ERR! enoent This is related to npm not being able to find a file.
  npm ERR! enoent
  </code></pre>
  <p>I've also tried the following at different times:</p>
  <ul>
  <li>Delete <code>node_modules</code> and reinstall npm</li>
  <li>Used npm 7.3.0's Git repository to create a new <code>npm</code> file (?) (I will need to find the suggestion online again to clarify/provide more specifics)</li>
  <li>Clean caches</li>
  <li>Uninstall and reinstall Angular 11 CLI and Node.js (tried for both LTS and Current version)</li>
  </ul>
  <p>Nothing has worked so far. The second method I tried in the above list was able to update it to 6.14.10, but this attempt returned errors that seemed to affect Angular. I reverted everything to the original state to be safe. Please let me know if I can clarify anything else regarding my issue.</p>
