So this way it works.

Which public key?  You may have several around...

This is the key you refer above?  This is probably the cause of the
problem, are all the different programs you are using as client using
the same pair of keys (public and private)?

Let's try a simple test:

In your client computer, in a terminal under your Cygwin user home
directory run the following

scp -o PubkeyAuthentication=no .ssh/id_dsa.pub myUser@10.4.15.5:tempKey
ssh -o PubkeyAuthentication=no myUser@10.4.15.5
cat tempKey >> .ssh/authorized_keys
exit
ssh myUser@10.4.15.5

Did that work as expected?

I don't know PuTTYgen or what's the deal with .ppk keys; know even less
about winSCP so no comments there.
