If your window and walls are wet in the wintertime, it means you have insufficient insulation and the cold isn't being stopped outside. Condensation forms when moist air meets cold surfaces. Moisture can breed mildew and mold if air isn't moving, so in areas of high moisture, use a fan at least to prevent mold growth and do a number of things when it is feasible.
1. Install an exhausting fan in your bathroom to remove excess moisture to the OUTSIDE OF THE HOUSE. Don't exhaust it into your attic.
2. Replace or add to the insulation in your walls
3. Replace old windows or add insulation in the cavities around them and cover them with plastic in the winter to help stop the cold surface from collecting moisture and trap air as an insulator.
If you don't address both the insulation and the moisture, it will form a larger problem as mold penetrates the drywall and fills the house with spores, causing serious health risks. At a bare minimum, get the fan installed to get the moisture out of the house.

If you are boiling potatoes, stop. If you are steaming spagetti, Stop. If you heat your house with hot water or steam, call out for evaluation and repairs. If you have anything generating hot waters and steam, that could be responsible for wet walls too.

If you have a relative humidity gauge or meter, make sure thatyour humidity doesn't exceed 15-18 percent.

proper indoor humidity is dependent on and should be adjusted/changed according to OUTSIDE temperature
as a 'rule of thumb'
winter: 25-40 %
summer: 45-55 %
"The key measure value is dewpoint... not RH.
At 70F indoors and 40%RH, any surface under 44F will condense the water vapor in the air. Lower that to 25% and now it's 32F. With windows, even if you get low-E argon filled jobs, you'll find that air leaks and the frames themselves have a lower R value than the glass, plus the aluminum reenforcment has a lot of mass."
