How to query for installed packaged COM extension points?
forderud80 Thank you for your question. We do have a public API that might help (ICatInformation::EnumClassesOfCategories (comcat.h) - Win32 apps | Microsoft Docs) for enumerating CLSIDs of:
- classes that implement a specified category, or
- all classes (by asking for -1 categories)
The results include both classes in HKCR\CLSID and Packaged COM, but there is no public API for querying Packaged COM specifically.

Thanks a lot Aditi! This was exactly what I'm looking for. 🙂
Do you know if there are also APIs for querying registry metadata for a COM class like Version, InprocServer32/LocalServer32 paths etc. that will include the Packaged COM catalog?
