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.

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.
