Thanks for the list, it looks good. Alternatively, there is the mingw
project, which offers also POSIX programs. I haven't tried either.

In order to make progress, I have installed MS Windows 10 in a virtual
machine, and I have bought an MS Windows license. This allows me to test
ssh and scp on MS Windows myself. Sadly, the sshd daemon does not start,
I need to figure out what's up.

Anyway, the Tramp test suite does not run through. Copying files with a
space in their file name, via scp, does not work. I guess it needs kind
of quoting, but I don't know which. See

--8<---------------cut here---------------start------------->8---
scp albinus@gandalf:/home/albinus/.emacs 
"c:/Users/albinus/AppData/Local/Temp/foo bar baz"
--8<---------------cut here---------------end--------------->8---

Quoting a local file name works.

--8<---------------cut here---------------start------------->8---
scp "c:/Users/albinus/AppData/Local/Temp/foo bar baz" 
albinus@gandalf:/home/albinus/tmp
--8<---------------cut here---------------end--------------->8---

This works also. "/home/albinus/tmp/foo bar baz" has appeared on the
remote machine.

--8<---------------cut here---------------start------------->8---
scp "c:/Users/albinus/AppData/Local/Temp/foo bar baz" 
"albinus@gandalf:/home/albinus/tmp/blub bla"
scp: ambiguous target
--8<---------------cut here---------------end--------------->8---

Doesn't work. Do you have an idea, which kind of quoting for the remote
target I need?
