After playing around with Windows 7 more, I'm happy to find that it does come with the usual games that were on Vista. You just have to activate them. Start button, > Control Panel, > Programs, Turn Windows features on or off. You select them one at a time. They are installed, but do not show up until they are activated.

Windows of course always had Solitaire going back to the 1986 version, and it became one of the greatest time wasters ever devised. But probably the real purpose of it was to get people to use the mouse.
