title: Registry Editing: How to calculate DWord Hex Values
body: <p>I'm trying to make some registry edits and I'm not sure I understand how specific dword values are calculated. </p>
  
  <p>Here are two examples:</p>
  
  <pre><code> [HKEY_CURRENT_USER\ControlPanel\Volume]
   "Volume"=dword:0xFFFFFFFF ; 0=off, 0xFFFFFFFF=maximum
  
   "Refresh"=dword:493E0 ; every 5 minutes
  </code></pre>
  
  <p>For the volume, how would I calculate what the range of options are if 0xFFFFFFFF is the max? And for "Refresh", if 493E0 is every 5 minutes, how do I figure out what every minute, or every day or every hour would be?</p>
