In the GPA and Kleopatra Backend-Preference you will find a check box
below the gpg-agent tab.  Thus no need to mess around with an editor.

Just don't start Pageant.  Putty looks for a tool which provides the
Pageant protocol and gpg-agent does just this.  Technically Putty looks
for a window named Pageant and communicates with the owner of that
window using WM_COPYDATA and a mapped file.

I have not done extensive tests but the protocol used by Putty is
identical to the one used by OpenSSH and thus gpg-agent should have no
problem to reply to all requests (except for v1 keys - but nobody uses
them anymore, right?).


Shalom-Salam,
