How can I prevent the store window reflections?
Recently, I took some pictures of the shop windows during the day. I do not use the flash. I used circular polarizing filter. I tried to take photos from different angles. But I could not get rid of the reflections of window. What I get rid of them? Or is there any way to fix this? Thank you. By the way, I Nikon D40x, 18-55mm AF-S DX Zoom-Nikkor Lens. PS: Please do not tell me turn flash off, or to take photos from different angles. I've tried. PS: I've said that, also used circular polarizing filter. 
If you can not disposing of them, taking from different angles and then using a polarizer, which sounds as if you are not using the polarizing filter properly. It is not just stay in front of the lens and taking photos. We must turn to the right position to cut the reflections (or as much as possible).
