OK, fair enough, it is an edge case... I am a stickler for correctness! :P

Looking at previous threads though actually, I notice that the
following is documented by Microsoft regarding the obcaseinsensitive
value:

"If this setting is enabled, case insensitivity is enforced for all
directory objects, symbolic links, and IO objects, including file
objects. Disabling this setting does not allow the Win32 subsystem to
become case sensitive."

You could just get away with therefore, in theory, a call to
NtOpenSymbolicLinkObject for \SYSTEMROOT. If it fails because it
cannot be found, you know that the system is running with case
sensitivity, otherwise, it is case sensitive.

Regards,

Nick
