Jeff, Dmitry,
Since any external program would deal with in fact internals of wine -- I never cannot be sure if I made a full snapshot of wine, or something change.
All your registry settings are under $WINEPREFIX, as well as all installed files, unless you installed them to a different mount point that is linked in your WINEPREFIX.
