Does WEC7 has support for IHV Extensions DLL and IHV UI Extensions DLL?

Hi All,

I am very new to WEC7. Exploring about Native Wifi Ihv Extension DLLs support on WEC7. As of now i came to know the following libraries and services are involved in Native WIFI Framework stack:

  1. nwifi.dll

  2. wlanmsm.dll - msm module

  3. wlansvc.dll - svc module

  4. wlanutil.dll - utilities

  5. wlanapi.dll - Api lib used by applications(wlantool)

  6. wlansec.dll - security module

  7. wlanext.exe - IHV extensibility service

  8. wlantool.exe - wlantool to configure wireless adapter.

  9. netui.dll - Network UI library

Please correct me if the above info is wrong. Here the question is about wlanext.exe(Wireless LAN 802.11 Extensibility Framework). Wlanext service is not started as part of native wifi stack initialization. This acts as an interface between the IHV Extension DLLs and the MSM(wlanmsm.dll) module. In Windows 7 svchost.exe starts the wlanext.exe service which is not available in WEC7. Please clear the below queries.

Who starts this wlanext service in WEC7 and WEC2013?

Is there any specific module we need to enable in catalog to support this feature?

The following is the debug log when i started it manually through command prompt:
