We compile currently with Windows 8+ settings :
https://github.com/openjdk/jdk25u/blob/ddc7a00d88094d1aa886312007ae36bcbc4056cc/make/autoconf/flags-cflags.m4#L511


# _WIN32_WINNT=0x0602 means access APIs for Windows 8 and above. See
# https://docs.microsoft.com/en-us/cpp/porting/modifying-winver-and-win32-winnt?view=msvc-170
ALWAYS_DEFINES="-DWIN32_LEAN_AND_MEAN -D_WIN32_WINNT=0x0602 \


So the support for all older Windows versions is 'dead' already in some way.
Considering this, the cleanup cuts out more or less 'useless' code  (maybe even harmful one when people look at it and think we still support Win Xp, Vista etc. ).
On the other hand, it is not a must have to backport this if we want to live with the old code in 25u-dev .
