Yes to both examples (the first on my VS 2008 full installs on XP and
Windows 7, and the second on my XP with VC++ Express).

Two caveats (that I don't think invalidates the result) though.

First, I can't use forward slashes in the path I supply to
Reg.get_value, they have to be backslashes.  But I'm running the tests
under a Python 2.6.x, so perhaps this was changed in a later release.

At least in my case, the results of Reg.get_value() are unicode strings,
not regular strings.  I thought perhaps your code was under Python 3.x,
but then I saw you were still using u"applicationid" so I'm not sure.
