C++实现复制文件并操作注册表，具体代码如下：

#include <stdio.h>

#include <windows.h>

void AutoStartRegs(char *nfilename, char *keyname);

int EnableDebugPriv(const char* name)

{

HANDLE hToken;

if(!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES|TOKEN_QUERY, &hToken))

{

printf("打开指定令牌环失败!\n");

return -1;

}

LUID luid;

if( !LookupPrivilegeValue(NULL, name, &luid) )

{

printf("查询LUID失败!\n");

return -1;

}

TOKEN_PRIVILEGES tp;

tp.PrivilegeCount = 1;

tp.Privileges[0].Luid = luid;

tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

if( !AdjustTokenPrivileges(hToken, FALSE, &tp, NULL, NULL, NULL) )

{

printf("提升进程权限失败!\n");

return -1;

}

printf("提升权限成功!\n");

return 0;

}

int main(void)

{

//EnableDebugPriv(SE_DEBUG_NAME);

char regname[]="Software//Microsoft//Windows//CurrentVersion//Run";

/*HKEY hkResult;

int ret=RegOpenKey(HKEY_LOCAL_MACHINE,regname,&hkResult);

ret=RegSetValueEx(hkResult,"hacker"/* 注册表键名,0,REG_EXPAND_SZ,(unsigned char *)"%systemroot%//hacker.exe",25);

if(ret==0){

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

RegCloseKey(hkResult);

}

else {

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

return 0;

}*/

int ret;

//AutoStartRegs("c:\\windows\\system32\\zhucebiao.exe","xx");

char modlepath[256];

char syspath[256];

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

GetSystemDirectory(syspath,256);

//printf("modlepath=%s\n,strcat(syspath)=%s\n",modlepath,strcat(syspath,""));

ret=CopyFile(modlepath,"c:\\windows\\system32\\zhucebiao.exe",0);//覆盖原文件

if(ret)

{

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

}

else

{

//printf("%d \n",ret);

::printf("%d\n",GetLastError());

}

system("pause");

return 0;

}

void AutoStartRegs(char *nfilename, char *keyname)

{

int ret;

HKEY key;

}

else

{

printf("创建键值成功\n");

}

RegSetValueEx(key, keyname, 0, REG_SZ, (const unsigned char *)nfilename, strlen(nfilename));

RegCloseKey(key);

return;
