Correct me if I am wrong, but Windows 7 by default does not install games.
These games are available as Windows Features, but you need to turn them on.
Steps:
- Press Start (Orb)
- Go to Control Panel
- Go to Programs and Features
- In left menu select "Turn Windows features on or off"
- Mark "Games" folder or individual game you want
- Press "OK" button
- Games will be installed
