title: How to change file association without UAC confirmation?
body: <p>When I was working with file association in a .NET application I hadn't had found a way to set it without UAC popping up a confirmation dialog.</p>
  
  <p>Today, when I opened uTorrent and looked up for file association, I've found that you can enable (writing to registry) without any confirmation from the UAC.</p>
  
  <p>How is that possible? uTorrent is not running as an admin.</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>Well, I have just discovered with <a href="http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx" rel="nofollow noreferrer">Process Monitor</a> (Sysinternals) that what uTorrent.exe does is to create a few keys (<strong>uTorrent</strong> and <strong>.torrent</strong>) but in <strong>HKCU</strong> (<code>HKEY_CURRENT_USER</code>), not in <code>HKEY_CLASSES_ROOT</code>.
  Anyways I also have those keys in <code>HKEY_CLASSES_ROOT</code> ... maybe the installer created those. Not sure.</p>
