Foggy windows on a cold morning? Where the fog is tells you what it means.
On the inside of the glass: there's too much moisture in the air, and it gets worse as the weather gets colder. Keep your blinds and curtains open a little so warm air reaches the glass, use your kitchen and bathroom fans, and run your HRV (air exchanger) if you have one.
Between the panes, where you can't wipe it off: the seal has failed, and that glass needs replacing.
