I'm in such a situation that every week I need to find one or two software names and all I know is CLSID. I want to ask if there is any official place where I could look for.

  • Are we talking about CLSIDs (for COM interfaces) or about GUIDs in general? Where did you get the CLSID from? – Werner Henze Oct 11 '13 at 13:17
  • @ST3 - I know of no database that would hold this information. I would use your current process. – Ramhound Oct 11 '13 at 13:42
  • @Werner I have some CLSIDs for COM interface. I have them from one registry cleaner. – ST3 Oct 11 '13 at 14:57

If you have a CLSID {xxx} you can take a look at the registry key HKEY_CLASSES_ROOT\CLSID\{xxx}\. The default value for the registry key will give you a description of the CLSID. Other values under the key will give you more information like the DLL that implements the interface and a short name (program ID).

There is an article on codeproject that gives you a good overview over the COM registry keys.
