Seems like a dumb question to me too but the first screen that comes up listing parts of the registry to uncheck for backup causes me to ask. I know what the registry looks like via the editor and these groupings don't register with me. I just want to make sure that if everything is checked that it means that the entire registry gets backed up. And, I guess, it begs the question for me as to why one would want the option of omitting any of these groups. Or maybe I'm just not understanding what the first screen's about at all. Thanks!
