You'll need to remove these along with the old putty before you can take the pane out of the frame. A paint scraper or tool like a chisel will work, but if you find that the putty's too hard to remove, gradually soften it using a heat gun. Hold the heat gun about one inch from the glass and move it around to spread the heat. Put doubled sheets of aluminum foil on the other panes to stop them from cracking due to the heat.
After you have removed the old glass, use a damp cloth and clean the inside of the window sash to remove any dirt or dust. You can now put in a new piece of glass.

Warm up a few tablespoons of putty and roll it into a 3/4-inch thick rope. Place the putty on one side of the rabbet and place the blade of your putty knife at a 45-degree angle to the frame's rabbet.

Pre-drilling the holes will prevent the nails from splitting through the molding. A well-stocked hardware store carries tiny bits that you can use to drill holes.

If the rabbets have become too rough to smooth using the putty knife, lightly sand them and brush on an exterior primer. This will stop the new glaze from absorbing moisture from the wood and shorten its life.
After the frame has been cleaned and prepared, rub the putty until it is soft and malleable. Use the putty knife apply a thin layer of it to the inside of the rabbets, forming an even bed for the glass to rest upon. Repeat the process for the remaining exposed edges.
After the putty is dry and the putty is removed, you can remove any remaining glazing points from the grooves within the sash. Before you attempt to remove them, you should wear a pair of safety goggles to shield yourself from glass shattering. A heat gun set to a low setting can help you gently warm and loosen the metal so that you can stretch it out of the frame with pliers.
