"German PC-Welt magazine reports that Microsoft used an illegal copy of SoundForge 4.5 (Google translation) for editing Wave files shipped with Windows Media Player. You can check that yourself by opening any file in the [Windows location] \Help\Tours\WindowsMediaPlayer\Audio\Wav\ folder in notepad or other editors of your choice and looking at the last line. There you will find a reference to SoundForge 4.5 and also a user called 'Deepz0ne' who happens to be one of the founders of an audio software cracking group called Radium."
