Windows support

Hi, I just installed the extension on a Windows PC. When the extension icon is clicked on in the left menu, an error message appears because the command "grep" doesn't exist in Windows:

Command failed: nvidia-smi --query | grep 'CUDA Version' | head -n 1 | sed -r 's/^.CUDA Version.: (\S*)/\1/g'
'grep' is not recognized as an internal or external command,
operable program or batch file.
