Answer 1

Most of the system CLSID are constant, to allow dynamic discovery of components; some COM components are using public CLSID.

For example, in DirectShow, filters are retrieved through their CLSID, to enable dynamic building of graphs.

Check the MSDN documentation about the CLSID you are interested in to see if it is publicly available and stable.
