Determine the component's CLSID from the registry using this key:

HKEY_CLASSES_ROOT\{component's progid}\CLSID

Then lookup the ThreadingModel using this registry key

HKEY_CLASSES_ROOT\CLSID\{component's clsid}\InprocServer32\ThreadingModel

The OLE/COM Object Viewer also shows the threading model for components.
