That's easy. Your RH is too high. If your furnace has a humidufier, turn it off.

I also had similar experiences with my brand new replacement windows(signature product of Clera windows). It is the below given ideas that helped me to get through it. Thanks to the website of *******. It is them who shared the details. Here, arranged from easy to more difficult, are the steps you should take to reduce condensation on your windows.
  • Install storm windows or replacement windows with double or triple glazing.
  • Shut off furnace humidifier and any other humidifying devices in your home.
  • Be sure that louvers in attic or basement crawl spaces are open and that they are large enough.
  • Run kitchen or other ventilating fans longer and more often than has been your custom.
  • Open fireplace damper to allow easier escape for moisture.
  • Air out your house a few minutes each day. Air out kitchen, laundry and bathrooms during use or just following use.
  • If troublesome condensation persists see your heating contractor about an outside air intake for your furnace; about venting of gas-burning heaters and appliances; or about installation of ventilating fans.

It can also be from air leaks around the windows.
Unlock the window and try to move the sash from side to side.
If there's more then about 1/16 of movement they may not be shimmed correctly.
Were these new, or replacement windows?
