Sorry, but what do you mean by nds games?

If you are referring to the games that come with Windows 7, you should be able to click the orb (Windows symbol), all programs, Games. Or Start Menu, Games on the right side.

If you do not have those options, you may have to go to Control Panel, Programs, Turn Windows Features on or off, and make sure Games it checked.
