This means github only supports public-key-based authentication
(the SSH protocol specifies at least three other, including a
widely-known password-based).  Since you did not add your github key to
your SSH key agent (pageant.exe from PuTTY), plink saw no usable
key and hence failed to authenticate you.

I somehow feel this will be the next obstacle you will run into
so after you fix GIT_SSH (we'll get to that in a moment), be sure
to read [1] which deals with generating and using SSH keys via PuTTY and
[2] which deals with associating those keys with your github account.

Well, Git precisely tells you what happened: it failed to execute
"C:\Putty\".  Does attempt to execute a directory appear to be OK to
you?  It shouldn't.  As I've told you in my previous response, the
GIT_SSH environment variable has to be set to the full pathname of the
plink.exe binary which is (probably) "C:\Putty\plink.exe" in your
particular case.

That's already enough.
