有兩種方法
一種是在安裝完sp2後再把不必要的服務關掉
開始>執行>services.msc
找到防火牆的選項再把它停用即可

ie的擋popup功能在工具>網際網路選項>隱私權

或是nlite也可對光碟作瘦身把你不想要的功能先從光碟內殺掉，安裝完後的xp才佔1g多的空間
但是nlite對中文版的xp有點問題

另外以下的服務都可視自己的需求將其停用歐~

謝謝您的回覆..........
小弟我有在用舊版的防火牆，
sp2的防火牆功能也不完整，
小弟我有在用F-secure 5.54，
雖然小弟我有在用F-secure 5.54了，
但還是想再開xp那個簡易的防火牆，
所以才不想要更新sp2的防火牆..........^^"
除了關掉之外，有辦法只更新hotfix嗎?



這些小弟有自己調整過了，
謝謝您的提醒.........^^

如果已經有防火牆了，最好把XP內建的關掉，以避免衝突產生....
