Siu Cheong你好
windows xp home edition 應該是可以 upgrade 到 vista or windows 7 的
windows vista home basic upgrade
http://store.microsoft.com/microsoft/Windows-Vista-Home-Basic-with-SP1-32-bit-Upgrade/product/17981D7F vista 你可以看看以下 url 個upgrade advisor 應該可以幫到你
http://www.microsoft.com/windows/windows-vista/get/upgrade-advisor.aspx windows7 home premium upgrade
http://store.microsoft.com/microsoft/Windows-7-Home-Premium-Upgrade/product/B0F9E641 install win7 你需要做一個clean install 的
個price 就可能要自己去shop 度看看 應該平過 full version 3分一既price 掛
你windows xml home edition 隻dvd 是不是自己買有box 的
如果是 或者可以打去 microsoft hong kong 果度問一問
Please forgive me in my concept is wrong.
Hope this can help.
