A couple more options for fixing this:

• Edit your Path system variable to contain the path to imagemagick as it's first content and then add the rest after it. This will make windows always find the imagemagic convert first before it finds the other convert program. So something like this: C:\Program Files\ImageMagick-6.9.2-Q16;C:\Program Files\Haskell Platform\2014.2.0.0\lib\extralibs\bin;...

• Another option is to create a dedicated folder somewhere on your machine where you will place shortcuts for some of these name clashes. Then what you do is that you rename those shortcuts to meaningful names, for example convert_image_magick, then add the path to this folder to your system path. So now as you hit tab more, you will finally find the right program you want to run
