title: Add a new file association in Windows 7
body: <p>With Windows XP I could use the Control Panel to add a new file extension, associate it with a program, and assign an icon to it.  I did that using Folder Options in the Control Panel.  Folder Options has a tab in it called "File Types".</p>
  
  <p>But Windows 7 Folder Options does not have that tab.  And the suggested place for file associations (Default Programs) does not let me add a new extension.</p>
  
  <p>How do I do what I want to (i.e. associate a new extension with an existing program and also apply a new icon to it)?</p>
