title: Is there a list for known CLSIDs of the windows registry?
body: <p>In the windows registry reside many CLSID values (in <code>HKEY_CLASSES_ROOT\CLSID</code>) such as <code>{16d51579-a30b-4c8b-a276-0ff4dc41e755}</code>, many of which may belong to widely known or even built-in applications or libraries. Is there a list or database that contains a mapping of these? </p>
  
  <p>Some usages would be, to present a more meaningful name in a registry viewer along with the key, or checking whether a particular application is present (or was present and not anymore) but has left some keys in the registry.</p>
