If you could use 'static const' as everywhere else and not 'const static'
that would be nice.

Why did you add size initialization here? If that wasn't done before there was
a reason for that.

Remove double sizeof(WCHAR) multiplcation here and everywhere else.

RegEnumKeyW takes number of characters, not bytes. Why did you
change that since your previous patch?

Please read documentation first, otherwise you are wasting your
and our time.
