Okay, Microsoft have officially gone too far now. That’s my C drive, it’s where I put my stuff. It’s mine. It is not, has never been and should never be a Windows system folder. Not to mention the fact that hiding files like this does not make the interface easier to use, it just introduces another mode that confuses users and makes users panic because they’re in some cryptic part of the OS that they shouldn’t be in. Fix the damn OS so it’s not so easy to inadvertantly break – don’t just hide the entire hard drive from the user.
