  I am one of the rare regular users of Windows OS in the core team,
but I must also confess that I am neither knowledgeable in TRegistry fields,
nor in all what concerns UniCode matters, which is still the main point
of those modifications...

  If nobody else steps up, I will try to look into it,
but I hope someone else from core team will be able to check and commit
those changes...
