Personally I prefer for everything to be visible, as I like to be able to see exactly what is on the system and I am interested in how Windows etc actually work. That's why I get annoyed with MS when they try to hide stuff, and trying to "simplify" Windows by doing things like adding that stupid new-style control panel option where all the "advanced" options are hidden and all you can do is change your wallpaper and things like that, and that ridiculous Security Centre thing that goes "you don't seem to be running anti-virus software" - yes I know I'm not running AV software, stupid Windows, I would remember if I'd installed one! If I really wanted to dedicate 90% of my system's resources to running Norton I'd have done it wihtout needing you to tell me, Windows! Grrrr! Sorry, that's just me ranting :p

I'm not especially technical either - don't be intimidated by it all!
