There are multiple strategies required. Water vapour condenses when warm, water-vapour air meets a much colder surface. Therefore one has to consider:
2) try to raise the temperature in the room if appropriate - to raise the surface temperature on the inside (of the window)

There are multiple strategies required. Water vapour condenses when warm, water-vapour air meets a much colder surface. Therefore one has to consider:
1) try and prevent some of the water vapour getting into the air at source
2) try to raise the temperature in the room if appropriate - to raise the surface temperature on the inside (of the window)
3) increase ventilation into the room - allowing air in which less water vapour is contained
4) insulate better those surfaces exposed to the very cold outside, so as to raise the surface temperature on the inside (the surface exposed to the moisture-laded air).
Numbers 2) and 3) work directly against one another - if you open the window, you may get drier air in, but you also get colder air in. So you see that there are trade-offs.
4) is impractical to do cheaply for windows - if you have DG already, all you can do is improve the quality (by changing to wider DG gaps - not what I am proposing for you - just trying to explain the problem completely).
1) you can do by a combination of extracting the moist air around hobs and showers at source before it gets all around the house, AND (possibly) Sandy's idea of a dehumifier.
2) is possible, but expensive on those bills - a better route would be to put more insulation in OTHER parts of the house which will raise the ambient temperature for the same energy cost.
Hope that helps explain the problem and some solutions. There isn't a silver-bullet solution during these cold times.
