A fairly technical overview is here:

Fully-virtualized can (in theory) run any OS ever written.
Para-virtualized can only run OS which have been ported to Xen (eg Linux
and some varities of Solaris & BSD)
At this time, paravirtualized is significantly faster than fullvirt so if
you have the option paravirt is always preferred. With Windows of course
you don''t have that option - fullvirt is only choice.
