This is why you sometimes get the warning message about unsigned drivers when you install new hardware - not everyone submits their drivers, though it could also just be that the driver you are installing is new and Microsoft hasn't signed off on it themselves yet. Microsoft has a program called WHQL (Windows Hardware Quality Labs) where manufacturers are invited to voluntarily submit the drivers they made so that Microsoft can test them in an asortment of various hardware configurations to test for bugs and stability, and when and if the submitted drivers pass the WHQL testing process Microsoft will digitally sign them and make them available on the Windows Update website. The manufacturer of the hardware itself is also who writes the driver for it. The reason that drivers are typically not included in Microsoft Service Packs is becuase Microsoft does not make drivers for hardware (except for Microsoft hardware, which it has been progressively pulling out of as well over the last 5 years particularly in regards to gaming accessories). It would be nice if SP3 would at least let me do this, but in every case I have to load my audio drivers and then SP3. Sometimes I like to reinstall my OS, install SP3 and then all my drivers, including the Realtek ones. I would also like to ask if the Realtek drivers could be included in SP3, rather than have to patch it later on.
