title: shutdown.exe parameters with dashes or slashes?
body: <p>I use a call of <code>shutdown.exe</code> to reboot machines having different versions of Windows installed.</p>
  
  <p>For Windows XP the command is:</p>
  
  <pre><code>shutdown.exe -r -f -t 01
  </code></pre>
  
  <p>For other versions of Windows I use:</p>
  
  <pre><code>shutdown.exe /L /R /C /Y /T:1
  </code></pre>
  
  <p>Now it seems, that the second command won't work on Windows XP. Does anybody know which versions of Windows support slashes and which dashes?</p>
  
  <p>EDIT:</p>
  
  <p>This is not an issue of wrong parameters. Here is a printout from an affected machine (German installation of Windows XP):</p>
  
  <pre><code>Microsoft Windows XP [Version 5.1.2600]
