 **                                 [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..                                                                                                                  **
