Is CUDA 8 (Toolkit) supported Windows 8 (Not 8.1)?

I was trying to install CUDA Toolkit 8 from this link https://developer.nvidia.com/cuda-downloads, but there doesn’t seem to be any download link for Windows 8. Furthermore, when I try to install using the net-install for Windows 8.1, there was a warning that my OS is not supported (which is Windows 8). So, is CUDA 8 (Toolkit) supported Windows 8 (Not 8.1)?

The installation also failed when using the net-install for Windows 8.1.

The supported operating systems for CUDA 8 on windows are listed here:

http://docs.nvidia.com/cuda/cuda-installation-guide-microsoft-windows/index.html#system-requirements

windows 8 is not listed.

Thanks
