自己寫腳本去更新WINDOWS UPDATE

之前我有寫過一篇文章 叫做 一次下載windows update 更新檔(windows update downloader)

這次我要講的是,直接透過腳本去下載windows update來安裝。

其實以前實驗過,像是直接透過windows update下載安裝更新與 我以前那個先把更新下載好在本地更新所花的時間比較過後發現。其實先下載好的還是比較快。

但是其實快沒多少,因為就快了下載的時間。而如果安裝時就有包到像是sp1那種更新的話,其實後續的更新也最多大約1G上下而已 下載時間節省的可能約10分鐘左右。(我的下載速度快) 而平常還要維護這個更新包,就會覺得cp值感覺就沒這麼好..

而最近在逛微軟的MSDN有發現,微軟其實有交怎用腳本的方式跑更新。

 

這對我來說感覺就方便多了。我可以寫一隻程式在灌完系統後,自動安裝所有我想要的軟體後自動更新 然後重開 在自動更新 再重開 直到完成為止。

微軟MSDN教學的網址 如下 https://msdn.microsoft.com/en-us/library/windows/desktop/aa387102%28v=vs.85%29.aspx

其實就是把下面這些CODE存成黨名叫做WUA_SearchDownloadInstall.vbs

然後再寫一個BAT檔 裡面寫的cscript WUA_SearchDownloadInstall.vbs

執行這個BAT檔就可以了。

你如果實際RUN過這個BAT檔你會發現 他下載完 還是會問你要不要確定更新

按Y開始更新這樣,你可以自行修改下面的腳本。就可以不用按Y 自動跑更新到結束了。

非常的方便。
