如何在Windows中自动销毁子进程？

#include<iostream>
#include<Windows.h>
#include <Tlhelp32.h>
#include<string>

using namespace std;

DWORD findProcessId(const string& processName) {
    PROCESSENTRY32 processInfo;
    processInfo.dwSize = sizeof(processInfo);

    HANDLE processesSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);
    if (processesSnapshot == INVALID_HANDLE_VALUE) {
        return 0;
    }

    Process32First(processesSnapshot, &processInfo);
    if (!processName.compare(processInfo.szExeFile)) {
        CloseHandle(processesSnapshot);
        return processInfo.th32ProcessID;
    }

    while (Process32Next(processesSnapshot, &processInfo)) {
        if (!processName.compare(processInfo.szExeFile)) {
            CloseHandle(processesSnapshot);
            return processInfo.th32ProcessID;
        }
    }

    CloseHandle(processesSnapshot);
    return 0;
}

int main() {
    string processName = "notepad.exe";
    DWORD processId = findProcessId(processName);

    if (processId != 0) {
        HANDLE processHandle = OpenProcess(PROCESS_TERMINATE, FALSE, processId);
        if (processHandle != NULL) {
            if (TerminateProcess(processHandle, 0)) {
                cout << "子进程 "<< processName << " 已成功销毁。"<< endl;
            } else {
                cout << "无法销毁子进程 "<< processName << "。"<< endl;
            }
            CloseHandle(processHandle);
        } else {
            cout << "无法打开子进程 "<< processName << "。"<< endl;
        }
    } else {
        cout << "未找到子进程 "<< processName << "。"<< endl;
    }

    return 0;
}
