Cold windows + humidity = condensation. If the windows are cold enough the condensation then freezes.

If there's enough airflow around the water/ice will evaporate/sublimate.

In my house there are a few windows where when it gets below -30 the condensation and freezing is fast enough to overcome the airflow and it builds up.

But it evaporates when it warms up, if it's a lot I'll just put a towel so it doesn't drip (though in one room the paint on the trim is already all flaking off, but a quick and and paint will fix that).

I'd rather do that then reduce the humidity in the house.

EDIT: Pointing a fan at it would probably help.
