It is some time since I messed around with Win batch files.
Are you sure there is not an error in the script used. Is it a modified version of this? https://gist.github.com/dbuscombe-usgs/6085758.
Do you need -b '(gimp-quit 0)' tacking on the end? as:
Another way is using Imagemagick - http://www.imagemagick.org this would need wrapping in a batch file to cycle through the images. For a single image.
Something like this for a folder of images. (In a Win 7 VM)

No windows expert but it seems to work Hopefully one of the Windows guys will come along.

magick input.png png8:output.png

Code:
for /r %x in (*.png) do magick "%x" "png8:%x_indexed.png"
