The games that come with Windows XP are pretty dated.  But with Windows Vista, Microsoft has gone back to the drawing board.  Included in Vista is a whole slew of updates to classics along with some new games including a pretty nice chess game.  Check out the screenshots below.

The new chess game is pretty impressive.	Minesweeper gets a much needed update	Mahjong! Yes!	I'm not quite sure what this game is..	Microsoft's dialogs are getting better.
Solitair gets an update too.
