Depends. Some older windows just need an adjustment, new hardware or weather stripping as they wear out over time. Sometimes, it is not worth it to have a window repaired as it is too far warped/damaged or parts are no longer available.

That is called a seal failure, which is when the dry air or argon in between your two panes of glass has escaped due to a tiny hole in the spacer and normal humid air fills the cavity. You will see it more often when there are cooler nights and warmer days (Fall/Spring) as the glass is being warmed and cooled around the 0 degree Celsius mark.

That is condensation. The glass in your window or door is your coldest surface of your house, with an R value of anywhere from 2 to 10; your walls can range from 4 to 28. Condensation occurs when the internal humid air of your home meets the cold surface, creating a beading of moisture. To control humidity, you need to allow air to circulate against the glass (curtains and blinds trap air), and/or reduce the humidity in your house. See Energy Star’s website for an article on humidity and how to control it.
