If the features offered by Wordpad are enough, there's no need to buy any program, because it comes with Windows 7. In fact, it already came with Windows 95 16 years ago, so you might already know it.
It offers both margins and fonts.
I'd start trying this one to see if it suits your needs.
I have Windows 7 on my computer. I am interested in purchasing an inexpensive word processor that will do simple things such as allow me to make notes to myself and easily allow me to copy and paste words from another program into it and allow me to easily set whatever margins and type face sizes I want. Does anyone know of such a word processor? Thank you very much. user470
