Wow!!

I confess that I have not tested this.  I think it is sufficiently
counterintuitive that it would be useful if you could submit a test that
would demonstrate it, e.g. put a non-SBCS string into the registry in
Unicode, query and get it back out, demonstrating that the size returned
is the number of lexical characters (plus 1 in Win95/98/me?).

And if this is the case then your original fix is still incorrect; we
would need to multiply the size not by sizeof(TCHAR) but by the maximum
number of bytes required to hold a lexical character (which is
presumably going to have to handle UTF-8).
