Delete different Audio, keep 1 on windows

Hi. I have video files that have different audio tracks in other languages. And i would like to have a batch file that would delete the audio files, but keep the one i want, thats in the videos. I know it can be made over the gui, but its hard doing that for a lot of files that has a lot of audio tracks.
I dont know any of the commands and i have hope that you guys can help me to write the batch file.
