I remember gloomily (haven't used windows since ages) that newer 
Windows versions don't like users to write directly to C:. Have you 
tried to save the file to your Documents folder?

no, it's the ssh-server denying a log on from 'root'

It looks to me more like an issue with path naming. Try 'c:/' instead
of 'c:', or use '/' to mean the root directory of the current drive.
Alternatively, do a web search for the problem and the symptoms, as
you're unlikely to be the first person to have run into this.

You are repating yourself.

How could possibly

     with open(localpath, 'wb') as fl:
PermissionError: [Errno 13] Permission denied: 'c:'

be a problem with the SSH server?

I'm going to go out on a limb and say that's pretty clearly not the
issue.  The exception states that the problem is one of permissions
on the C:

  PermissionError: [Errno 13] Permission denied: 'c:'

which ishish clearly identified as a "Windows doesn't let you do that
any more" issue.  Additionally, I don't know off the top of my if the
Paramiko libraries expect a file-name, or if they expect a directory
into which the file gets put based on the server-side name.

The best solution is to do as ishish proposed: write the file to some
other appropriate (i.e., writable) location.  A simple fix might be

  import os
  # ...
  localpath = os.path.expanduser('~')

or

  localpath = os.path.join(
    os.path.expanduser('~'),
    'passwd.txt',
    )

A stop-gap solution might be to just run the program in a writable
directory:

  c:\> cd %TEMP%
  c:\...\TEMP> python myprog.py

A far worse solution would be to run the script as Administrator on
the Win32 box, which will grant permission to write in the root of C:

-tkc

windows systems dont usualy have an SSH server & root is not a normal 
windows user name

on most systems that DO have a ssh server root logins are usually 
prohibited, either enable root logins (dangerous) or log in with a user 
that has permissions to do what you require. if you don't have access to 
the server then you need assistance from someone who is authorised.

Just for the record, you can enable root logins but disallow password
logins, so root has to be done with a public/private key-pair.

That said, I do as you describe and still SSH to my ssh-user account,
then "su" to root as needed from there.  But at least there's a
middle ground that isn't as vulnerable as putting a root account out
there to be banged on by any script-o-matic bot that finds it.

I also like to change my external SSH port to something
non-traditional (and have configured port-knocking in the past) to
prevent the obvious pokes I would otherwise see in my sshd/auth/access
logs.

I've done both of these. Most of my boxes don't have passwords on the
root account AND don't allow SSH to root, relying on a sudo-enabled
account usually; and it's perfectly possible to also deny password
access to *any* account via SSH. Quite good for security... though it
can create an awkward bootstrap problem if you lose all private keys
that had access.
