Do you see the same result if you invoke 'echo' from the cmd prompt?
IOW, does this mean Windows 10 changed the behavior of the built-in
'echo', and it now removes trailing whitespace from its argument?  If
that's the reason, how about modifying the test so that it expects the
correct result depending on the value returned by x-server-version?
