Then I don't think I understand the backtrace you posted.  It seems to
indicate that Trump signals a "failed to connect" error, but the error
message you cited, i.e.

  'plink' is not recognised as an internal or external command, operable
  program or batch file.

is the message shown by the Windows cmd.exe shell, it is not a Tramp
error message.  So it looks like the backtrace does not really show
the relevant error?  Could you perhaps produce a backtrace that is
more relevant to the problem you are having?
