程序比较简单，用到了C语言获得自身路径和系统路径，修改注册表项等，某些函数不理解可以查看MSDN

1 #include
     
       2 #include
      
        3  4 char *GetFilename(char *p)  //得到一个路径的纯文件名 5 { 6     int x=strlen(p); 7     char ch='\\'; 8     char *q=strrchr(p,ch); 9     return q;10 }11 12 13 int main()14 {15     char *filepath;16     char modlepath[256];17     char syspath[256];18 19     //打开酷狗应用20     filepath="C:\\Program^ Files\\KuGou\\KGMusic\\KuGou.exe";  21     system(filepath);22 23     //将程序移动到系统目录下24 25     GetModuleFileName(0,modlepath,256); //获得自身路径26     GetSystemDirectory(syspath,256);  //得到系统路径27 28     int ret=CopyFile(modlepath,strcat(syspath,GetFilename(modlepath)),1);//复制，CopyFile的第二个参数是目标文件名29     if(ret)30     {31         printf("%s has been copyed to sys dir %s\n",modlepath,syspath);32     }33     else34     {35         printf("%s is exists",modlepath);36     }37 38     //程序添加开机自启动39     char regname[]="Software\\Microsoft\\Windows\\CurrentVersion\\Run";40     HKEY hKey;41     ret=RegOpenKey(HKEY_LOCAL_MACHINE,regname,&hKey);       //打开注册表键42     ret=RegSetValueEx(hKey,"MyProm",0,REG_EXPAND_SZ,(unsigned char*)strcat(syspath,GetFilename(modlepath)),25);  //设置键值43 44     if(ret==0)45     {46         printf("succes to write run key.\n");47         RegCloseKey(hKey);48     }49     else50     {51         printf("failed to open regedit.%d\n",ret);52         return 0;53     }54     55     return 0;56 }
