Windows depend on the what kind were installed. The following is from www.energystar.gov:
If you replaced any windows, doors, or skylights—or installed new ones that have earned the ENERGY STAR label—you may be eligible for a tax credit of 10 percent of the cost (not including installation) on up to $200 for windows and skylights and up to $500 for doors.
Driveway would not qualify.
