Blu-ray support is not achieved by drivers.... it is supported by Blu-Ray compatible software. You will have to get one of the newer burning softwares like Nero or Roxio. I'm using the latest version of Nero and it has support for Blu-Ray built in.
The Microsoft drivers are the only drivers available for optical drives. Microsoft built-in native drivers with the OS and that's all that's required other than the burning software.
