Windows 服务不捕获关机事件 C/C++

Question

我创建了一个小型 Windows 服务来捕获一些事件，包括系统关闭。每次我关闭计算机时，服务事件都不会被调用。但是当我重新启动计算机时，该事件正常工作。

我已经尝试使用：SERVICE_ACCEPT_PRESHUTDOWN + SERVICE_CONTROL_PRESHUTDOWN，但没有成功。

我怎样才能捕捉到计算机关机事件？

Ps：编译后我使用以下命令注册服务：sc.exe create "ZSimpleService" binPath = "C:\path\ZSimpleService.exe"

编辑 1：我使用的是 Windows 10

代码：

SERVICE_STATUS g_ServiceStatus = { 0 };
SERVICE_STATUS_HANDLE g_StatusHandle = NULL;
HANDLE g_ServiceStopEvent = INVALID_HANDLE_VALUE;

VOID WINAPI ServiceMain(DWORD argc, LPTSTR *argv);
DWORD WINAPI ServiceWorkerThread(LPVOID lpParam);
DWORD WINAPI CtrlHandlerEx(DWORD CtrlCode, DWORD eventType, LPVOID eventData, LPVOID context);

#define SERVICE_NAME _T("ZSimpleService")

VOID WINAPI ServiceMain(DWORD argc, LPTSTR *argv) {

    g_StatusHandle = RegisterServiceCtrlHandlerEx(SERVICE_NAME, CtrlHandlerEx,
    NULL);

    if (g_StatusHandle == NULL) {
        goto EXIT;
    }

    // Tell the service controller we are starting
    ZeroMemory( & g_ServiceStatus, sizeof(g_ServiceStatus));

    g_ServiceStatus.dwServiceType = SERVICE_WIN32_OWN_PROCESS;
    g_ServiceStatus.dwControlsAccepted = SERVICE_ACCEPT_STOP
            | SERVICE_ACCEPT_POWEREVENT | SERVICE_ACCEPT_SESSIONCHANGE
            | SERVICE_ACCEPT_SHUTDOWN;
    g_ServiceStatus.dwCurrentState = SERVICE_START_PENDING;
    g_ServiceStatus.dwWin32ExitCode = 0;
    g_ServiceStatus.dwServiceSpecificExitCode = 0;
    g_ServiceStatus.dwCheckPoint = 0;

    if (SetServiceStatus(g_StatusHandle, &g_ServiceStatus) == FALSE) {

启用快速启动选项后​​，单击开始菜单->关机将使机器进入睡眠模式/休眠状态而不是关机。但重启菜单不受影响。 （我们已经发现，从命令行关闭也不会受到影响。）

所以你可以禁用快速启动来解决这个问题。
