        ^^^^^^^^^^^^^^^^^^^^^^^[1]    ^^^^^^^^^^^^^^^^^^^^^^^^^^[2]

First off, if [1] works, something's seriously wrong with your system.
c:\cygwin\usr\bin should be empty, and all of the executables you find in
/usr/bin under Cygwin (notably bash) should be in c:\cygwin\bin.

Secondly, the way you specified the path ([2] above) is not going to work
in bash.  You really want to specify a POSIX path to your script.

Oh, really?  Assuming the above is not a typo, you're not running the
Cygwin bash.  The latest version that comes with Cygwin is 3.1, which uses
"bash-3.1$" as its default prompt.  In fact, that's the latest official
release of bash, too.

Sorry, I can't quite parse the above.  Can you please describe the exact
steps you've taken to run the script?  Perhaps even with a small
self-contained script example?

The usual way (that would also replicate the environment you have in your
shell) is 'c:\cygwin\bin\bash.exe -l -c "/path/to/script.sh"'.  However,
you might want to also make sure that your PATH is set up correctly,
especially if you plan to do this through the Windows scheduler.  Also
note that the Windows scheduler will run your script as the SYSTEM user,
not as the user you normally use to log in.
HTH,
