You're not going to be able to believe your ears when you find out that nine of the WAV audio files located in the Help\Tours\WindowsMediaPlayer\Audio\Wav directory in the Windows installation media were created using a cracked version of Sound Forge 4.5! Whilst I certainly haven't checked yet, Tomshardware swears that if you open the files in a HEX editor or with notepad, the last line signature reads "000-04-06 IENG Deepz0ne ISFT Sound Forge 4.5" which has been confirmed by Tom's sources as genuine, and belonging to the cracker Deepz0ne. It’s not entirely certain where this one could go, given that its not too clear who is liable legally.
