Define "readable".  The permission you're concerned about is the
executable permission.  The read permission is set as
expected.  The fact that Windows chooses to set the executable
permission on data files is simply a feature they employ to make
associated programs run from the command line (cmd.exe) when you
invoke the data file.  Cygwin doesn't do this but regardless, this
is the only functionality I know of that could be affected by the
executable permission not being set.

I'm always suspicious of Windows upgrades, especially when things start
going wrong afterwards.  Another thing to consider are changes in other
third-party security software.  It would also be worthwhile to look at
the permissions on these problem files as Windows sees them, either with
'cacls' or Cygwin's 'getfacl'.
