word processor for XP

There are two free word processors on the internet that
will open and store documents in all sorts of formats
including .doc . A very basic and easy to use one is
Abiword. A more fully functional one that is being
constantly updated as an open source project(anyone can
write new add ins for it) is Open Office. Open Office is
beginning to rival Office XP in it's functionality. Either
one will do a marvelous job for you and work perfectly in
XP without any conflict and are full proof to install.
Good luck.
