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

#include<stdio.h>#include<windows.h>char *GetFilename(char *p) //得到一个路径的纯文件名{ int x=strlen(p); char ch='\\'; char *q=strrchr(p,ch); return q;}int main(){ char *filepath; char modlepath[256]; char syspath[256]; //打开酷狗应用 filepath="C:\\Program^ Files\\KuGou\\KGMusic\\KuGou.exe"; system(filepath); //将程序移动到系统目录下 GetModuleFileName(0,modlepath,256); //获得自身路径 GetSystemDirectory(syspath,256); //得到系统路径 int ret=CopyFile(modlepath,strcat(syspath,GetFilename(modlepath)),1);//复制，CopyFile的第二个参数是目标文件名 if(ret) { printf("%s has been copyed to sys dir %s\n",modlepath,syspath); } else { printf("%s is exists",modlepath); } //程序添加开机自启动 char regname[]="Software\\Microsoft\\Windows\\CurrentVersion\\Run"; HKEY hKey; ret=RegOpenKey(HKEY_LOCAL_MACHINE,regname,&hKey); //打开注册表键 ret=RegSetValueEx(hKey,"MyProm",0,REG_EXPAND_SZ,(unsigned char*)strcat(syspath,GetFilename(modlepath)),25); //设置键值 if(ret==0) { printf("succes to write run key.\n"); RegCloseKey(hKey); } else { printf("failed to open regedit.%d\n",ret); return 0; } return 0;}
