title: Create custom culture without registering it
body: <p>Is it possible to create a custom culture without registering it in Windows? Every solution and documentation refers to <a href="http://msdn.microsoft.com/en-us/library/system.globalization.cultureandregioninfobuilder.aspx" rel="nofollow">CultureAndRegionInfoBuilder</a> class with calling <code>Register</code> after new culture has been created. But registration of custom culture alters cultures visible in OS and besides it requires admin privileges.</p>
  
  <p>If it's not possible there're two ways to avoid registering a new culture:</p>
  
  <ol>
  <li>avoid using custom culture as long as possible, i.e. stick to standard cultures. It can work for now, but I don't know for how long.</li>
  <li>register custom culture during application install. This is not the option since we can't guarantee admin privileges since we would like to update application remotely.</li>
  </ol>
  
  <p>Are there any ways? </p>
