2、如果找不到Software Protection服務,那麼我們可以參考如下方案,通過導入Software Protection鍵值,重建Software Protection服務,來解決該問題:
3、新建一個記事本文件,將以下文字復制粘貼到記事本中,以“SP.reg”命名並保存於桌面。

4、請您雙擊“SP.reg”,當系統提示您是否確認導入注冊表時,請點擊“是”。之後會有提示說明已經成功導入注冊表。
5、重啟後,再次進入”服務”控制面板查看,可以找到Software Protection服務,右擊並選擇啟用。
Software Protection是一個重要的服務,Win8系統提示無效的產品密鑰,且報錯0x80070424都是由此服務丟失導致的,用戶通過上述方法,導入修改注冊表便可恢復這項服務。
