I have got multiple questions about vista:

What is the difference between retail and OEM Windows Vista Ultimate?

For Windows Vista Ultimate Upgrade do you have to have windows xp already installed on your computer or do you just have to have the cd?

Also what is the difference between a 32-bit Operating Sytem and a 64-bit System?

For what reasons will I need a 64-bit Operaing System?
