Stop window condensation by lowering indoor humidity, keeping air moving, and warming the glass. ENERGY STAR says condensation forms when the window surface is colder than the dew point of the humid indoor air, so the fix is not just wiping the water off. It is changing the room conditions that let the water form there in the first place.
Run bath and kitchen exhaust fans, vent the dryer outside, and use a dehumidifier if the room stays damp. Open blinds or curtains during the day so warm room air can reach the glass, and make sure furniture is not blocking airflow near the window. If the problem keeps coming back, better insulation, weatherstripping, or more efficient windows will help because a warmer window surface is less likely to sweat.
