Microsoft Uses Pirated Software
Members of a former software cracking group have discovered that audio files created with one of its cracked programs are distributed with each copy of the Windows XP.
The files are at @%windir%\Help\Tours\WindowsMediaPlayer\Audio\Wav@
directory of Windows XP. If these files are opened with a HEX editor (or any Text Editor for that matter) the code contains the signature “Deepz0ne”, who was a member of former cracking group “Radium”.
