Having bought a new computer, I was initially delighted to find it came with windows 8 already installed. I found it childish, cumbersome and with all the games missing. I've just started to play chess and was relying on the titan chess game that (I assumed) came with 8. My decision is made by by windows.
You play the old Windows 7 solitaire games, including Chess Titans, in Windows 8. See http://www.howtogeek.com/122145/what-happened-to-solitaire-and-minesweeper-in-windows-8/?utm_source=newsletter&utm_medium=email&utm_campaign=200812
But note that as Chess software goes, Microsoft Chess Titans is extremely poor. There are several much better alternatives, such and Fritz and Rybka.
