C++调用关机等操作是的提权操作

//提权
BOOL EnableShutDwonPriv()
{
    HANDLE hToken = nullptr;
    TOKEN_PRIVILEGES tkp = {};
    BOOL bRet = FALSE;
    do
    {
        if (!OpenProcessToken(GetCurrentProcess(),
            TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
            break;

        if (!LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,
            &tkp.Privileges[0].Luid))
            break;

        tkp.PrivilegeCount = 1; // one privilege to set
        tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

        // Get the shutdown privilege for this process.

        AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,
            (PTOKEN_PRIVILEGES)NULL, 0);

        if (GetLastError() != ERROR_SUCCESS)
            break;

        bRet = TRUE;

    } while (FALSE);

    if (FALSE == bRet)
    {
        SetLastError(GetLastError());
    }

    if (hToken)
    {
        CloseHandle(hToken);
    }

    return bRet;
}

//操作计算机
BOOL ReSetWindow(DWORD dwFlags)
{

    BOOL bRet = FALSE;
    do
    {
        if (EnableShutDwonPriv())
        {

                break;
        }
        bRet = TRUE;

    } while (FALSE);

    return bRet;
    //调用exitwindows来关闭系统
}
