How can I play my old Windows 7 games in Windows 10?

One of the most common complaints about Windows 10 is that it doesn't include the usual selection of free Microsoft games such as Solitaire, Minesweeper, FreeCell and Chess Titans. There are several possible solutions

I am missing the free games such as Chess Titans, Solitaire and a few more that Windows 10 doesn't have. I tried to install Chess Titans from Windows 7 but it won't let me. Are we likely to get it on 10 in the future? Veronica

The games have vanished. Where is my Solitaire? Oh, I can go to the Window Store and purchase a souped-up (ie ruined) Solitaire, but that costs money. For Solitaire? Crikey! Jim

Microsoft uses games partly for educational purposes: for example, Solitaire taught a generation to use the mouse to drag-and-drop. (There's an excellent post about this by James Hunt.) With Windows 8 and 10, Microsoft moved the games to the Windows Store. This should have taught users to log on and download them.
