When starting with an empty build tree (or more precisely with empty cache)
the logic of the "default generator" is implement in:

Source/cmake.cxx::int cmake::ActualConfigure()

There is some system dependent macro logic and in
the Windows case the code comment says
(if not in Borland or Cygwin or Mingw case):
// Try to find the newest VS installed on the computer and
// use that as a default if -G is not specified

So no, as far as I understand the code,
there is no registry entry that could possibly be set to force a
particular default.

I guess it shouldn't be that hard to implement but it is not there.
(I'm not willing to try myself because I'm not a Windows user/developer)

Nevertheless, may be you can explain us why you would like to setup a default?
Is it too painful to add the extra -G argument?
