WINDOWS2003 查密码软件源程序

//********************************************************************************
// Version: V1.0
// Coder: WinEggDrop
// Date Release: 12/15/2004
// Purpose: To Demonstrate Searching Logon User Password On 2003 Box,The Method
// Used Is Pretty Unwise,But This May Be The Only Way To Review The
// Logon User's Password On Windows 2003.
// Test PlatForm: Windows 2003
// Compiled On: VC++ 6.0
