I'm not sure what you did wrong but apparently you did.  I just tried
the following crude script:

========= SNIP =========
#!/usr/bin/expect -f
set timeout 10

spawn ssh mycygwinbox
expect {
  "myusername@mycygwinbox's password: " { }
  default {
    send_user "Spawning failed\n"
    exit
  }
}

send "mypassword\n"
expect {
  -re ".*\\$.* " { }
  default {
    send_user "Sending password failed\n"
    exit
  }
}

send "ls\n"
expect {
  -re ".*\\$.* " { }
  default {
    send_user "Sending ls failed\n"
    exit
  }
}

send "exit\n"
expect {
  -re ".*Connection to mycygwinbox closed.*" { }
  default {
    send_user "Sending exit failed\n"
    exit
  }
}
========= SNAP =========

and it worked perfectly fine, from a Windows console window as well as from
a ssh session itself.  The first two regexps are expecting my prompt, btw.
