Win2000的CMD漏洞.你是不是经常在开始菜单的运行窗口里运行命令呢?win2000和xp在执行搜索的时候, 首先查找根目录。而开始菜单的运行窗口里执行命令, 也是首先在系统盘的根目录里进行查找.这个漏洞其实是已经是公开的秘密了.本程序功能是：加一个加超级管理员用户和执行cmd.exe的功能.-Win2000 loopholes. You are not always at the beginning of the operation of the menu window for running order? WIN2000 and xp in the implementation of the search, the first find the root directory. The menu began operation in implementing the order window, the system is the first set of root directory for you. The flaw is in fact is already an open secret. This program functions : Add a plus super admin users cmd.exe and implementation of the function.

DLL 的应用实例,很清晰,一看就会DLL的使用了-DLL application example, it is clear, one will watch the use of a DLL

The first component is a physical memory allocator for the kernel, so that the kernel can allocate memory and later free it. Your allocator will operate in units of 4096 bytes, called pages. Your task will be to maintain data structures that record which physical pages are free and which are allocated, and how many processes are sharing each allocated page. You will also write the routines to allocate and free pages of memory. The second component of memory management is virtual memory, which maps the virtual addresses used by kernel and user software to addresses in physical memory. The x86 hardware memory management unit (MMU) performs the mapping when instructions use memory, consulting a set of page tables. You will modify JOS to set up the MMU page tables according to a specification we provide.
