I have recently got a new computer with Vista HomePremium. The Works Word processor which is part of the system does not have the same features as Word on my old ME system and is not as easy to use. Do I need to install my old Word 2000 ?
If you want the features of Word then you will need to install your Word 2000.
It should work OK under Vista.
It will also work alongside Works.
(You say Works is part of the system, but it is not part of Vista, it is part of Microsoft Works which is a separate package that can be installed on top of Vista and is often given away "free" with Vista).
