How to uninstall Windows Vista?

1) 如果你係用Windows Vista Business
你可以問返供應商(VENDOR), 佢地同MICROSOFT有做DOWNGRADE 服務, 可以DOWNGRADE返做WINDOWS XP, 這方法可保留你所有電腦資料, DRIVER也肯定有

2) 如果你係用Windows Vista 其他版本
你或者重新買隻XP或甚他OS, 重新INSTALL WINDOWS! 放隻碟入去BOOT起佢就得了, 但不能保留你的電腦資料, DRIVER也未必有
Start Windows XP, install and launch VistaBootPro. Go to Manage OS Entries and then select the Microsoft Windows Vista entry. Click on the Delete button and confirm that you want to delete Windows Vista from the BCD Registry.
