Use the recommended local System account and you should have no problems
with recent Cygwin services under recent Windows:
"To run multiple users, cron must change user context without knowing
the passwords. There are three methods to do that, as explained in
If all the cron users have executed "passwd -R" (see man passwd),
which provides access to network drives, or if you are using the
[obsolete] cyglsa package, then cron should run under the
local system account."
Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
