I tried a fresh install of cygwin (after stashing away the old version
(with move, but I skipped the unmoust since I use the default mounts
anyway)) with setup.exe version 2.562 (from the snapshots).  Oddly,
while sh.exe is now being created and the prompt is the colored one
that Cygwin usually sets, /etc/passwd is not being created.  I am
uncertain whether this is the same bug manifested in a new way or if
it might be a new bug.  (Obligatory grumble about Vista being a pain.)

Did you check your /etc/passwd?  I only noticed it b/c when I started
the shell my home directory was set to C:\Users\<my_user> instead of
C:\cygwin\home\<my_user>.  (C:\Users is Vista's version of what in XP
is C:\Documents and Settings.)
