Look to see if your furnace has a humidity control. Sometimes these are on the side of the furnace, sometimes they are controlled by a digital thermostat. Humidity in winter is a wonderful thing, but sometimes it can be set too high, and the moist air will condense onto cold glass. Not only does this potentially damage windows, but can lead to a situation where the humidifier is calling for more humidity but the level isn’t reached because moisture is being pulled out of the air by the windows. For this reason humidity in winter should be around 25%.

Others have said you can dehumidify a room, but this is rarely a problem in chicago in the winter, especially with double lanes glass, which is what you have. I’m nearly certain you have a built in humidifier on your HVAC and it hasn’t been set for a lower winter level.
