If the IGU seal fails the condensation will form between the two glass panes, which can lead to fogging and decreasing the window's ability to withstand heat. Defogging IGUs can be accomplished in many methods, including using an instrument to defog. However, these kits can't replace the inert gas, therefore the insulation benefits of the window cannot be replaced.
To defog double-pane windows remove the vinyl stoppers around the frame. These can be easily removed with a razor or a small amount of putty. Next, wipe off any old putty on the edges of the frame. Then apply a fresh roll of double-sticky tape to the frame's edges, making sure that it covers all corners. Then, press the window pane into the frame until it is stuck. Finally, add caulking to the rabbets that are exposed.
Broken seals
Window seals are the seals that hold each glass pane in a double- or triple-pane window. A broken seal is characterized by a window with an appearance of condensation or fogginess that is not able to be removed. Window seals are susceptible to break because of the natural process of expansion and contraction of your windows. This happens when sunlight heats your window which causes it to expand and push air out through the semi-permeable seals. Then, when the window cools in the evening, it contracts again, bringing in humid air and moisture that could cause the seal to fail.

After replacing the glass frames and sash can be caulked to seal them together. This will stop water from leaking through and causing damage to the frame. It is essential to use a waterproof caulk so that the damage doesn't get worse.

Broken locks or handles
If your windows aren't closing properly this could be costing you money in lost heat, and possibly putting your home at risk of burglars. A quick inspection can identify if it's a loose handle or lock that's causing the problem.
If you have a tilt-and-turn window (used on dual-action uPVC windows) then you'll likely have a spindle handle that locks with shoot bolts in the frame of the window. These are normally hidden away behind caps made of plastic that are removed with the help of a Stanley knife.
This type of handle has the spindle which operates an internal mechanism within the window frame, pushing the handle's nose across an elongated block to secure the shoot bolt. If this is broken, then the window won't shut, and it may only open a few centimetres for ventilation.
Check if it still latches by pushing the handle at 90 degrees. If not, the lock isn't working and must be replaced.

You can accomplish this by gently pulling the beading from the frame using a putty knife. It may be necessary to apply some more force to get it off completely, but it should come off easily.
After the beading and sealant is removed and the sealant removed, you can begin to remove the damaged glass.
