Does the executable exist as "C:\Programs\PUTTy\plink.exe" ? 

I have this on a Win7 64bit box, but it should work for 32bit too:

(when (eq system-type 'windows-nt)
  (let ((dir (expand-file-name "PuTTY" (or (getenv "ProgramFiles(x86)")
                                           (getenv "ProgramFiles")))))
    (add-to-list 'exec-path dir)
    (let ((case-fold-search t) (path (getenv "PATH")))
      (unless (string-match (regexp-quote dir) path)
        (setenv "PATH" (concat dir path-separator path))))))

(setq tramp-default-method "pscp")

A quick test shows that the "plink" method works for me, but "plinkx"
gives me problems - you will need to experiment. Setting tramp-verbose
can help with diagnosing problems.
