@Zoron, as reply to your question above: The settings that were wiped out occasionally were for uTorrent, Yahoo! Messenger, Opera and WinAMP. WinAMP and Yahoo! Messenger they normally store their settings in \Users\AppData\Virtual Store\ or some other location under the AppData folder, etc etc. At moments, these folders went blank and their contents were moved to other location, impossible for the program itself to find them. This happened both under Vista and 7, x64.
