封鎖 Windows XP Service Pack 2

Microsoft Corporation 的 The Scripting Guys

此指令碼可遠端封鎖或解除封鎖從 Windows Update 網站或透過「自動更新」傳送 Windows XP Service Pack 2 (SP2) 的動作。封鎖 Windows XP SP2 的傳送動作是有時間限制的。如需暫時停用透過 Windows Update 及「自動更新」傳送 Service Pack 2 之過期日及詳細資料的相關資訊,請參閱 http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/sp2aumng.mspx (英文)。

若要使用指令碼,請複製程式碼,將它貼入 [記事本],然後將指令碼儲存為 .vbs 副檔名 (例如 blockxpsp2.vbs)。執行指令碼時,請在指令碼名稱後面加上參數:若要封鎖,請使用 /b,若要解除封鎖,請使用 /u。您也可以選擇包括遠端電腦名稱作為第二個參數。如果不指定遠端電腦,指令碼就會在本機電腦上執行。例如:

cscript blockxpsp2.vbs /b client1

如果電腦上的預設指令碼主機是 Cscript.exe,就可以省略開頭的 "cscript"。
