As others have said, it is doubtful there is anything wrong with your windows. Even the best windows have a much lower R value then your walls do, so when the temperature difference between your warmer inside air and the colder outside air is high, you will get condensation.

Newer homes are more moisture laden. Also, it is important to use your bath exhaust fans when taking showers, etc. Also, if your range vent exhausts outside, use it when cooking if what you are cooking is making steam. Homes are tighter now then they were 50 years ago, so exhaust fans should be used if humidity levels are high. As already said, a dehumidifier in extreme cases will help.

Maintaining some air movement and keeping blinds open will also help. The problem is much less here in Florida then up north, where it could be below zero outside and 70 degrees in the house. I have seen frost and ice form on northern windows, even insulated ones.

It truly is all about your humidity level, and the difference between the inside and outside temps. Remember, there is a healthy balance one wants to achieve. Too little moisture in the air and you will get "shocks" and furniture joints could open up, etc. Nosebleeds could occur. Cold air holds less moisture, so this is what Northerners face every winter. Some actually have Humidifiers to put MORE moisture in the air during the winter.

We are luckier. Our Florida air is normally much more humid....but we will get condensation on our windows on the few "cold" days we get this time of year. It is usually easily manageable.

Hope this helps!
