If the window has wooden moldings that hold the pane in place and you want to remove them, you can gently pry these pieces off with the flat end of a prybar if the window is framed with wood.
After the old pane has been removed, clean the area and prepare it for the new one. Use a wire bristle brush to smooth out the grooved channel where the window is installed. Clean any remaining sash or putty. Apply a bit of heat with a heat gun to melt the old putty, making it easier to scrape off and remove.
Measure the width and length of the opening in the sash and subtract 1/16 inch from each measurement. This will ensure that the replacement pane is slightly smaller than the opening, so that it can expand and contract with changes in temperature. Roll a rope of glazier's putty around the perimeter of the new pane, then press it firmly into the grooved channels in the frame.
