Broken Glass
Cracked windows aren't just unsightly but can also let valuable sunlight and heat to escape your home. It's possible to fix the glass that is cracked without replacing the entire window.

After cutting your new glass, apply glaziers' compound around the edges of the frame and glass. Once the compound dries paint it over to match the rest of the frame.
Condensation on the Inside of Double Glazed Windows

Condensation of the outside of double-glazed windows is rare, but it can occur when the seal has started to break down between the glass and the frame. This is more common in winter as the temperature is lower and it's more likely for condensation to form. The most likely cause is a defect in the spacer that is placed between the window and the frame. The spacer is filled with desiccant which is highly absorbent and will soak up any moisture that is present.
This could lead to moisture leaking into the gap when the desiccant has been saturated. This could cause condensation and water to build within the gap, which is difficult to remove.
The good news is that most trustworthy window manufacturers will provide warranties on their products. They will replace the window unit and glass when it's damaged by condensation. Inform any issues as quickly as you can to the window manufacturer to ensure that the condensation is repaired as quickly as possible to prevent further damage.

Take measurements of the width and height of the opening both ways, then order the double-strength piece of glass that is 1/8 inch smaller in both directions. You'll also need to purchase glass points, which are metal triangles which keep the glass in the right place.
With the window sash out of the way, carefully pull it off of the wood molding with a flat pry bar. You may need to scrape old glazing off using a utility knife or chisel. Utilize the heat gun to warm any putty that isn't able to be removed easily. This will make it easier to remove it.
