(20點)在電腦中心買過windows vista home premium的請進。

You want正版,I think Home Premium is about $18XX to $21XX.But I remember you may use Windows Anytime Upgrade to upgrade to Ultimate free.The mans upstairs,the asker want正版,you can't use copy!!

Hope you will choose me to be the best answer!!!

幾百至一千幾,太便宜的是翻版貨.

對唔住，我只能用左20元買一隻Windowa Vista Ultimate付兩隻DVD。官方價錢太貴買唔。所以只能買電腦中心買嘅價錢Windowa Vista Ultimate64位及Windowa Vista Ultimate32位兩隻只買30元。
