Free Word Processing Software List

Ciao from Dallas! This is my first post here and though you folks all seem very pleasant and extremely well informed I hope I don't have to spend lots of time here. I would rather be enjoying my new computer rather than reading about how it works and how to get it to work, if you know what I mean. My computer uses are very limited by most standards (internet, email and some word processing for the most part with simple audio/video and photo work occasionally) so I prefer stuff that allows me to easily and repeatably get the job done with a minimum of fuss and struggle. With that here's the short story and the questions.

Lucky me, I had to replace my eight year old computer last week. Big change smacking me in the face! Even the new keyboard is taking some getting used to. I had no idea, nor did the salesperson mention, there were multiple versions of Vista to contend with until I began re-installing software I had used for years. Not everything likes 64bit! ...........
