使用win8系統(tǒng)的時(shí)候，總是會(huì)碰到這樣那樣的問題，比如最近有win8系統(tǒng)用戶到本站反映說，他在使用win8系統(tǒng)的過程中，突然彈出一個(gè)無效的產(chǎn)品密鑰的窗口，并提示0x80070424錯(cuò)誤代碼，指定的服務(wù)未安裝，這是怎么回事呢，針對這個(gè)問題，接下來小編就給大家分享一下Win8系統(tǒng)彈出無效的產(chǎn)品密鑰0x80070424錯(cuò)誤代碼的具體解決方法吧。

原因分析：這個(gè)問題的可能性是Software Protection服務(wù)丟失，即在services中無法找到該服務(wù)。

解決方法：

1、按”Win+R”組合鍵，調(diào)出運(yùn)行框，輸入: services.msc 并回車，查找Software Protection服務(wù)；

2、如果找不到Software Protection服務(wù)，那么我們可以參考如下方案，通過導(dǎo)入Software Protection鍵值，重建Software Protection服務(wù)，來解決該問題；
3、新建一個(gè)記事本文件，將以下文字復(fù)制粘貼到記事本中，以“SP.reg”命名并保存于桌面；

4、請您雙擊“SP.reg”，當(dāng)系統(tǒng)提示您是否確認(rèn)導(dǎo)入注冊表時(shí)，請點(diǎn)擊“是”。之后會(huì)有提示說明已經(jīng)成功導(dǎo)入注冊表。

5、重啟后，再次進(jìn)入”服務(wù)”控制面板查看，可以找到Software Protection服務(wù)，右擊并選擇啟用。
6、Software Protection服務(wù)是一個(gè)很重要的服務(wù)，用戶檢查更新報(bào)錯(cuò)0x80070424，也有可能是因?yàn)樵摲?wù)丟失導(dǎo)致的無法正常更新，可以通過上述方法恢復(fù)該服務(wù)來解決問題。

    通過上面的方法就可以幫助大家解決Win8系統(tǒng)彈出無效的產(chǎn)品密鑰0x80070424錯(cuò)誤代碼這個(gè)問題了，有碰到這樣問題的用戶們可以參照上面的方法步驟來解決就可以了。
