Condensation mainly occurs in the inside of your window during the winters because of the temperature difference. The temperature inside the room is hotter than the temperature outside. The warmer moist air inside the room comes in contact with the cold window glass and this results in condensation. The water present in the air within the hotter room quickly condenses when it comes in contact with the cold window glass. If the inside of the room is kept more warm by using room heaters, then the condensation in the window glass will be more. This is the main reason behind the widows becoming sweaty inside the warm room during the winter.
