If the cracks were not caused by mechanical damage, or a sudden impact on the window, they can be repaired by using epoxy and elbow grease. Follow the manufacturer's instructions and scrub the crack by using a damp cotton cloth. Then, apply epoxy to the crack. Allow the epoxy to fully dry before sanding and painting over the repaired area.

A simple strip of masking tap can also be used to stop a crack from spreading. A single strip of masking tape applied to both sides of the crack should suffice to stop superficial cracks from spreading, for instance stress-cracks caused by low temperatures.
