I'm doing a factory reset on my windows 7 computer. It's fairly new, maybe 2-3 years old, but windows 7 is bad about slowly grinding to a halt, lol.

I know to back up the basics, like documents, pictures, movies, songs, and personal files, but no where I look ever mentions anything else.

I also know that I need to back up "configuration files" whatever those are, my appdata folder, and "installation" files. Don't know how to, but will figure it out.

Is there anything else important/pertinent/convenient that I need to back up that will make it easier to set my computer back up?
