title: Use powershell tabexpansion function
body: <p>When I run the statement <code>man tabexpansion</code> it shows that I simply need to provide -line and -lastword.</p>
  
  <p>However, when I run a statement like this:</p>
  
  <pre><code>tabexpansion -line "c:/win" -lastword "c:/win"
  </code></pre>
  
  <p>It returns nothing.</p>
  
  <p>Shouldn't it show at least C:\Windows? What am I doing wrong?</p>
