I found the registry located at:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\WIC

Try to create instance by:

CComPtr<IWICImagingFactory> pImagingFactory;

HRESULT hr = CoCreateInstance(CLSID_WICImagingFactory, 0, CLSCTX_INPROC_SERVER,
                              IID_IWICImagingFactory, (void**)&pImagingFactory);
if (SUCCEEDED(hr) && pImagingFactory != NULL)
{
    pImagingFactory.Release();
    pImagingFactory = NULL;
    return false;
}
