Definitive registry- and file information for IM Apps and Websites

Hello, I need definitive information for Windows 7 both 32- and 64 bit for the following applications/websites. Specifically, I need to know, for each item, where and how it stores webcam information, specifically default camera setting, but as much information as possible really. A simple text file describing this information will do for delivery. Windows Live Messenger Yahoo Messenger AIM / AOL Instant Messenger (others that I will add later) I can already tell you from my own research that Yahoo Messenger appears to encrypt (or at least encode) the information it stores, so this isn't a simple case of Process Monitor telling you everythign you need to know. Serious bidders only please. Any questions/comments please ask.
