title: WSL2: Why do I have to shutdown WSL to restart WSL after restarting PC
body: <p>I have my windows set up WSL with Ubuntu. It has been working fine for a while, until I upgraded to WSL2.</p>
  <p>The problem is: every time I start up my PC (or restarting my PC), it lost the connection from Ubuntu to Windows drives.</p>
  <p>I got the message like this:</p>
  <pre><code>cd: Input/output error: /mnt/d/
  </code></pre>
  <p>The above problem could be solved easily by running this:</p>
  <pre><code>wsl.exe --shutdown
  </code></pre>
  <p>I want to solve this problem permanently, instead of shutting down WSL every time I got the problem.</p>
  <p>Any idea how to fix this permanently?</p>
