Rich removed the window from PD on Friday. The basics steps for the removal are the following:

0. PD in a socket, it helps;

1. In the beginning you open the screws on the cutter up so they just hold the photodiode;

2. Make a light little line first at desired height and make sure that it is a circle and not a helix;

3. You do not want to go start right away full force on it, you want to make tiny little incremental cuts. Eventually it just falls apart;
