Find that shutter jingle irritating? Here's how you can remove it,

Open the registry editor > navigate to the following key
Modify the ShutterSound to a number greater than 2 shall do the work. However, if you modify the sound settings in the camera, you will have to modify the registry again.

Another persistant solution, you got to find a wave file that playback nothing! (There's a silence.wav located in the windows directory) Decide on which shutter jingle you are going to replace. Rename your silent wave file to Shutter0X.wav where X is the number corresponding to the shutter jingle in the camera settings.  Copy this file into the windows directory and voila! Your camera remains quiet when taking photos
