查找进程

bool FindProcess(std::string strProcessName, DWORD& nPid)
{

	TCHAR tszProcess[64] = { 0 };
	lstrcpy(tszProcess, _T(strProcessName.c_str()));
	//查找进程
	STARTUPINFO st;
	PROCESS_INFORMATION pi;
	PROCESSENTRY32 ps;
	HANDLE hSnapshot;
	memset(&st, 0, sizeof(STARTUPINFO));
	st.cb = sizeof(STARTUPINFO);
	memset(&ps, 0, sizeof(PROCESSENTRY32));
	ps.dwSize = sizeof(PROCESSENTRY32);
	memset(&pi, 0, sizeof(PROCESS_INFORMATION));
	// 遍历进程 
	hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
	if (hSnapshot == INVALID_HANDLE_VALUE)
		return false;
	if (!Process32First(hSnapshot, &ps))
		return false;
	do {
		if (lstrcmp(ps.szExeFile, tszProcess) == 0)
		{
			//找到制定的程序
			nPid = ps.th32ProcessID;
			CloseHandle(hSnapshot);
			printf("找到进程: %s\n", tszProcess);
			return true;
			//getchar();
			//return dwPid;
		}
	} while (Process32Next(hSnapshot, &ps));
	CloseHandle(hSnapshot);
	return false;
}

 杀死进程

bool KillProcess(DWORD dwPid)
{
	printf("Kill进程Pid = %d\n", dwPid); 
	//关闭进程
	HANDLE killHandle = OpenProcess(PROCESS_TERMINATE | PROCESS_QUERY_INFORMATION |   // Required by Alpha
		PROCESS_CREATE_THREAD |   // For CreateRemoteThread
		PROCESS_VM_OPERATION |   // For VirtualAllocEx/VirtualFreeEx
		PROCESS_VM_WRITE,             // For WriteProcessMemory);
		FALSE, dwPid);
	if (killHandle == NULL)
		return false;
	TerminateProcess(killHandle, 0);
	return true;
}

开启进程

bool StartPrcess(std::string strProcessName)
{
	TCHAR tszProcess[64] = { 0 };
	lstrcpy(tszProcess, _T(strProcessName.c_str()));
	//启动程序
	SHELLEXECUTEINFO shellInfo;
	memset(&shellInfo, 0, sizeof(SHELLEXECUTEINFO));
	shellInfo.cbSize = sizeof(SHELLEXECUTEINFO);
	shellInfo.fMask = NULL;
	shellInfo.hwnd = NULL;
	shellInfo.lpVerb = NULL;
	shellInfo.lpFile = tszProcess;                      // 执行的程序名(绝对路径)
	shellInfo.lpParameters = NULL;
	shellInfo.lpDirectory = NULL;
	shellInfo.nShow = SW_MINIMIZE;                      //SW_SHOWNORMAL 全屏显示这个程序
	shellInfo.hInstApp = NULL;
	printf("程序自动重启中.... \n");
	ShellExecuteEx(&shellInfo);

	return true;
}

 提升权限

void EnableDebugPriv() {
	HANDLE hToken;
	TOKEN_PRIVILEGES tkp;
	OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken);
	LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid);
	tkp.PrivilegeCount = 1;
	tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
	AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, NULL, NULL);
	CloseHandle(hToken);
}

主函数

int main()
{

	std::string str_exe_name = "notepad.exe";
	DWORD nPid;
	FindProcess(str_exe_name, nPid);
	EnableDebugPriv();
	KillProcess(nPid);

	return 0;
