雙擊 IE 彈出「開啟方式」對話框？兩種註冊表修復法

桌面 IE 圖示雙擊不開網頁反跳「開啟方式」，通常是檔案關聯註冊表項損壞。提供兩種修復方案，建議先試方案一。

方案一：匯入修復註冊表檔（推薦）

1. 新建文字文件，貼入下列內容，存為 IERepair.reg。
2. 雙擊執行，確認匯入登錄表，重啟電腦即可。

方案二：從正常電腦複製 IE 程式資料夾

1. 正常電腦 C:\Program Files\Internet Explorer\ 整個資料夾複製過來覆蓋。
2. 若系統架構不同（x86/x64）請對應 Program Files (x86)。

成因分析

常見於安裝/解除安裝第三方瀏覽器、優化大師修改檔案關聯、惡意軟體劫持 .html/.url 關聯導致 IE 的 CLSID 註冊表項遺失或錯誤。
