Recently I took a course on line for Word. They informed us it was being
taught from VISTA and that a lot of the applications were not available on
XP. Is this true and how do we make the 2 act the same
I think you got your software names scrambled.
Windows Vista is an operating system, and Windows XP is the version before that.
Neither of them has any bearing on what "applications" (maybe you mean
features?) are present in any version of Word that runs on those operating
systems.
Office 2007, the most recent version of Office, includes Word 2007. The version
before that was Office 2003, and the version before that was (confusingly)
Office XP which contained Word 2002. Any or all of these Office versions will
run on either Windows XP or Windows Vista.
There is a big difference in some of the features (*not* applications, which is
another word for "programs") between Office 2003 and Office 2007. This doesn't
depend on which version of Windows they're running on. And if this is the
difference you referred to, you can't make them "act the same".
