Or even vista, I have a computer that had vista and did fine, I now have a couple with win 7 and it runs great, have a new laptop I got the wife thats touch screen that has win 8 its take some getting use to but has not been bad she has complained about it. If you have room increase the memory it will help, with it running slow, also use a external hard drive to keep and store your other stuff, and try to keep less stuff on the hard drive it will run better as well. My current laptop I have now when I got it, I also got think its a 1 tera byte external hard drive and store all my files on it, and if need something I transfer it, to use then take it off, and mine still runs like the day I got it.
