@darius Putty does seem to be “retired to a farm upstate”. It was a great tool for a long time, but hasn’t kept up to date, is no longer supported by its original author and newer alternatives are often recommended.

Windows 10 has the (real) OpenSSH client built-in and out of the box these days (and an OpenSSH server as an easy to install optional feature). I don’t know of GUI tools like WinSCP to take advantage of it though.
