在 Windows 上安裝 Apache 做作業，無法啟動：“請求的操作失敗！”

所以我只是設置了 Apache 來做一些網路作業。當我轉到http://localhost時，它顯示“它有效！” 但是當我到達http://localhost/index.html（該頁面的位置）時，我收到“無法連接”錯誤（Firefox）。當我去http://localhost/test.php時也一樣

當我打開 Apache Monitor 時，我點擊開始，然後點擊是 UAC 後顯示“請求的操作失敗！”

這是錯誤日誌：

以管理員身份執行 Apache或禁用 UAC。Apache 的執行緒受到作業系統的限制。
