microsoft uses pirate copies?
As you can see, this wave file (C:\WINDOWS\Help\Tours\WindowsMediaPlayer\Audio\Wav\wmpaud2.wav) ends with a signature from Deepz0ne. People say that this is a member of the crackinggroup Radium and this serial was published by that group! The used program is, as you can see, Sound Forge 4,5.
So this might get Microsoft in some trouble!
