Thankyou Brad for your very clear explanation. This nicely explains the
difference between the Windows and Linux systems.

Hard links are probably more useful on Windows since (I believe), they
do not require elevated privs:

I belive symlinks require privs because there ~all Windows programs do
not guard against symlink redirection attacks (usually TOCTOU). And
since Windows doesn't really have atomic filesystem operations, there's
~no way avoid TOCTOU.
