Do you have access to the server sshd log?  It could be faster to find
out why sshd is closing the connection in there.

My guess is that your authorized_keys is corrupted or has invalid keys
or perhaps more than one key per client is nor allowed (I wasn't sure
about this last one when I wrote my first reply)... so you can move it
to one side and make a new authorized_keys with only the key you copied
following my test:

mv .ssh/authorized_keys .ssh/authorized_keys.old
cat tempKey > .ssh/authorized_keys

This time is not append but create/overwrite.

If that still doesn't work then perhaps your Cygwin home is on a DOS
style (Fat32) file system, i.e. with CR-LF line endings and sshd chokes
on that.
