Condensation on windows is caused from your house being too humid during the winter when your windows are cold.
Dual pane/insulated windows will be much less likely to have this problem than old single pane windows. Upgrading the windows will probably solve the issue.
If you are stuck with old, single pane windows, and replacing them is not an option, then the other option is to try and reduce the humidity in the house. You could run a dehumidifier, but a better option would be to evacuate the humidity via ventilation to the outdoors. Humidity typically comes from your bathrooms, stovetop ranges, and washer and dryer. Ideally, each of those rooms or appliances should be properly ventilated to the outside.
