How do i convert a m4a file to an mp3 or windows's media supported file?

This is actually very simple.

One way to convert the file is to download "Total Video Converter". This will let you convert anything to anything. This is a paid program, however. If you do not want to pay or to download any software, you can go to http://www.zamzar.com/ and follow the on-screen instructions to convert this file for free.

If you simply want to open and play the file you can download VLC Media Player for free by going to http://www.videolan.org/vlc. This player will play any type of video or sound file. If you want something made for music, and more Windows Media Player style you can download WinAmp for free at http://www.winamp.com/ and enjoy all types of sound files.

So, the choice is yours, you can either download a program to open it, or convert it and play it in Windows Media Player. Either way is easy, and either way is free!
