Win8 Office 提示「無法驗證應用程式授權」？修復 Software Protection 服務登錄

Windows 8 使用 Office 開啟檔案時彈出「無法驗證此應用程式的授權」，通常是 Software Protection 服務 (sppsvc) 登錄損毀導致服務無法啟動。透過匯入正確登錄值即可修復。

原因分析

使用優化工具清理登錄、停用服務後，導致 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sppsvc 登錄鍵值遺失或錯誤，服務呈現「已停用」狀態。

解決方案：匯入修復登錄檔

1. 開啟記事本，複製以下完整登錄內容儲存為 sppsvc_fix.reg：

2. 雙擊執行 sppsvc_fix.reg → 「是」匯入登錄。
   
   
   
3. 重新開機或在「服務」中啟動 Software Protection 服務。
   
   
4. 開啟 Office 測試是否恢復正常。
   

此方法修復 sppsvc 服務登錄配置，恢復授權驗證功能，避免重裝 Office 或系統。
