你的代码存在如下bug:未定义标识符PROCESS_MEMORY_COUNTERS和GetProcessMemoryInfo

非常抱歉，您所指出的问题是由于我在代码中未添加必要的头文件所致，以下是修复后的代码：

#include <iostream>
#include <windows.h>
#include <tlhelp32.h>
#include <psapi.h>

using namespace std;

int main() {
    HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
    PROCESSENTRY32 pe32;
    pe32.dwSize = sizeof(PROCESSENTRY32);
    BOOL bMore = Process32First(hSnapshot, &pe32);

    cout << "Process List:" << endl;
    while (bMore) {
        cout << "Process Name: " << pe32.szExeFile << endl;
        cout << "PID: " << pe32.th32ProcessID << endl;
        HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, pe32.th32ProcessID);
        if (hProcess) {
            PROCESS_MEMORY_COUNTERS pmc;
            if (GetProcessMemoryInfo(hProcess, &pmc, sizeof(pmc))) {
                cout << "Working Set Size: " << pmc.WorkingSetSize / 1024 << "KB" << endl;
            }
            CloseHandle(hProcess);
        }
        bMore = Process32Next(hSnapshot, &pe32);
    }
    CloseHandle(hSnapshot);

    return 0;
}

在代码中添加了 `psapi.h` 头文件，该头文件中定义了 `PROCESS_MEMORY_COUNTERS` 和 `GetProcessMemoryInfo`。这样就可以解决未定义标识符的问题了。感谢您指出代码中的漏洞！
