The following commands were taken from the internet, I will give acknowledge when found:
Windows version now uses "magick" as the command:
magick vlcsnap-1280-07-14-21h45m00s867.png -crop 400x360+0+0 i1.png
magick ... # in place of `convert`
magick identify ... # in place of `identify`
magick mogrify ... # in place of `mogrify`
magick compare ... # in place of `compare`
magick compose ... # in place of `compose`
