Do you actually have any idea what the registry does, what a journaling file system is (note: Windows has journaling exactly the same way OS X does, Metadata-only) or what the "self maintaining" scripts do? Without googling now.
I've never in my 7 years+ of using Windows had a file system corruptions, in fact I've never had file system corruption on any OS apart from OS X, leading me to believe these "self maintaining" scripts are there as a stop-gap measure until the horrible mess that HFS Plus is can be fixed.
Which is never.
