How do you download Writer which is basically a copy of Word, but it's free.?

Answer 1

Open Office:
http://www.openoffice.org/

Answer 2

Try the free, and M$-Office compatible, Open Office from:

Included: Writer (like Word), Calc (Excel), Impress (PowerPoint), Base (Access), Draw (M$-Paint) and Math

Just make sure that if you want others to be able to view the documents using M$-Office Word, for example, save them using "Save as..." in .doc format, instead of the default .odt format. Or use the built-in PDF creation feature.
