It looks like a placebo pseudo-solution. The registry key is still there, now CC doesn't show it to you.
From CC:
Problem | Data | Registry Key
ActiveX/COM Issue | LocalServer32\C:\Windows\SysWOW64\Speech_OneCore\Common\SpeechRuntime.exe -ToastNotifier | HKCR\CLSID\{265b1075-d22b-41eb-bc97-87568f3e6dab}
The Registry Key is a short for
Computer\HKEY_CLASSES_ROOT\CLSID\{265b1075-d22b-41eb-bc97-87568f3e6dab}
If you look for it you'll find it for sure. We are still in the same starting point, but now like blinds with no help from CC.
