How about splitting apart initialization of Vinitial_environment and
Vprocess_environment and moving the former earlier so that it's
unaffected by Emacs' manipulations of the environment? See attached
patch.

To me it makes sense to have $HOME map to $USERPROFILE, and $APPDATA
is like $XDG_CONFIG_HOME (usually ~/.config/ on GNU/Linux). However,
this is purely subjective as there are no platform recommendations
about translating environment variables to other platforms.
