我換ｏ左個新電腦～
我問人借ｏ左個正版ｏ既　ｗｉｎｄｏｗ～
ｕｎｃｌｅ　幫我　ｓｅｔ　好哂ｏ野～
所以ｏ既　ｐｒｏｇｒａｍ　都係正版ｏ架～
但係當我　ｕｐｄａｔｅ　ｏ既時候～
佢話我唔　ｐａｓｓ　個正版　ｔｅｓｔ　喎～
連　ｍｅｄｉａ　ｐｌａｙｅｒ　都唔比我用～
點解呢？？

大家有無試過咁ｏ既　ｃａｓｅ？？
可唔可以幫ｏ下我？？

借來的正版?  係唔係個 registeration key 已經被用左呢?

唉 .... 妳中o左 microsoft 的奸計啦!! 由 XP SP2開始, 只要product key己經注冊過, 己經唔可以再用! 無論妳用正版定反版都係一樣!! 因為每次 windows update 都會check 個 product key! 妳依家可做o既係 --

1). 從新裝過一個翻版及每何update都一定唔好跟microsoft安裝;
2). 係公司搵一台新機 (一定要係brand name, e.g. Dell , HP ... etc.), 再抄佢地個 product key 比自己部機用.

as above, can't use product key that already registered,
1st solution: just don't use update, download media player in some other downloading site
2nd solution: just call up microsoft, they probably have a toll-free number provided to u when it said it fails, just call them up and tell them u ar using a legal copy, they will ask u product key and help u change the product registration to ur comp, but ur friend will suffer same problem if he reformat since now the registraion points to ur comp
3rd solution: purchase a new product key
