Yes, this seems to be the defect.

Ah, good, please use pinentry-qt4 then!

Two methods:
Copy pinentry.exe over or use the right gpg-agent.conf as you did
in your other email.

I think you cannot. This is a property of the operating system.
Background: GnuPG runs on several operating systems. Secure memory usually 
means that the memory will not get swapped to disc and maybe is harder to 
read by other processes, I am not entirely sure.
GnuPG will have to pull some tricks to make this possible, usually.
So currently I believe this is not possible on windows. If we knew the right 
tricks, maybe it will be in the future. Note that the windows platform has 
other security issues, so fixing this particular issue might not help much.

Just ignore this warning for now.

Best Regards,
Bernhard
