No, that's not right.  The registry setting is necessary since it
decides about the *kernel's* handling of casesensitivity.  And the
default is set to casesensitive=off.

I never understood why Microsoft invented this registry setting with XP.
The decision is usually done in two places anyway, FS-capability,
application case insensitivity request, and now there is the additional
registry setting which enforces caseinsensitivity on the kernel.  This
blog points to a possible reason:
