As a result of my post the other day for the best free software for Macs, I got a few requests for free software for Windows users. And although I have not used a Windows machine in years, here is what I could come up with by looking around and asking friends who are Windows users. I am no Windows pro, so let me know if there is anything else that should be added to the list (or taken off)!
Word / Spreadsheet Processing
MPlayer for Windows
