A little research I did brought up this  and this . The two
actually contradict each other in a small detail ( says this
registry setting only applies to SUA and  says it applies to the
whole POSIX layer) but they agree on the most crucial point: functions
in the Win32 API ignore this setting; in particular,  says the only
knob CreateFile[AW]() has to request POSIX-compatible behaviour simply
does not work starting with Windows XP, and indeed  says that
the POSIX subsystem was removed from the NT series of kernels starting
with Windows XP/Windows Server 2003. This subsystem (and the whole
"subsystem" thing, actually) was not really used by any visible project
so they decided to kill the whole concept, I reckon (more information
is available in , if you like).

I understand this, but you see, there's such thing as technical
obstacles you can't really overcome or the cost of doing so it
prohibitive. So I'd negotiate with the project's "owners" about taking
measures to remedy the situation without rewriting Windows.

Judging from the above arguments, I'm afraid, you can't: Git for
Windows does not rely on a POSIX compatibility layer (like Cygwin tools
do) and calls to Win32 API almost directly. "Almost" is because yes,
MinGW does provide certain kludges to make software coming from POSIX
feel better at home, and quite possibly some of them are used by Git
for Windows, but the whole point of GfW is being a native Windows
application, not relying on any compatibility layers, which means it
can't really escape peculiarities of its target OS.
If you feel like it, you might ask this question on the mailing list
dedicated to the GfW development  and possibly get an answer from
someone with direct experience with the GfW code base.
