Found the solution by experimentation:
The GPA executable is gpa.exe (surprise!) in the GnuPG directory.
I also found that if I send it a file on the command line it opens up
the File Manager window rather than the key manager that is otherwise

So I have added the following to the registry to get a context menu
item when selecting a file, which opens the GPA file manager. From
there I can easily select the operation to be performed.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\*\shell\GPA Manager]

[HKEY_CLASSES_ROOT\*\shell\GPA Manager\command]
@="C:\\Programs\\GnuPG\\gpa.exe \"%1\""

As you can see I have installed Gpg4Win *outside* the Program Files
directory tree in order not to have Windows messing with my files.

Hope this helps other Win7X64 users....'
