Eric,
Yes, I know you have Windows XP Professional. That is the "operating
system."
Microsoft Office is a completely separate product, and if you buy it,
depending on the package you pick, will provide you with Word, Excel,
et. al. Refer to the web site URL I gave you.
You must have Windows (XP, 2000, or maybe WIndows 98 but that is way out
of date) to run Office. The current version of Office you should be
looking at is Microsoft Office 2003. Pick the "package" with the
features you want. Again, see the web site URL I gave you.
It is a simple question. But you are going to have to look at this web
site URL I gave you and learn the difference between the products
Windows XP Professional, and Microsoft Office 2003 (Professional,
Standard, Small Business, and Academic).
If you have no real reason to pick Office ... and I think this because
you give no indication that you really know what Office is ... save some
money and use Open Office (
www.openoffice.org) for free, or use the
cost-effective Star Office from Sun.
Hope this is useful to you. Let us know.
