Howto: reset IE security zone settings programmatically

Internet Explorer 7 introduced the IInternetZoneManagerEx2 interface, which has a FixUnsecureSettings method to reset all security zone settings. Like all other IInternetZoneManager* interfaces, you can query this interface from the internet zone manager object:

IInternetZoneManagerEx2* pzoneManager=NULL;

HRESULT hr=CoCreateInstance(CLSID_InternetZoneManager ,NULL,CLSCTX_INPROC_SERVER,IID_IInternetZoneManagerEx2,(LPVOID*)&pzoneManager);
if(hr==S_OK && pzoneManager!=NULL)

There’s another CoInternetCreateZoneManager function to get the zone manager object’s IInternetZoneManager interface.
