Windows 10 I was using this until recently and have initialized it. It's quite old, so I only used it for things like research, so I don't know much about it. There are some scratches on the surface, but you can't really see them unless you look closely because of the color and pattern. I'll also include a mouse and a case. The case has quite a bit of wear and tear, so I can leave it out if you don't want it.
