Detecting which driver is installed

Can someone from NVIDIA driver team please clarify the following:

  • What is the proper way of detecting which driver flavor is installed on Windows platform?

NVIDIA has 4 driver flavors – Standard, DCH, Game Ready, and Studio. We need an officially supported way of detecting which driver is currently installed. So far it seems to be possible to identify DCH drivers using a registry key, but there is no known way of detecting Studio (CRD) .vs. Game Ready (GRD) drivers.

This information is important for diagnostics tools and troubleshooting, as well as for 3rd party automatic driver download / update tools which need a way to determine the correct driver to download and install.

Please advise.
