SSH clients have been easy on Windows for at least 20 years: just use Putty. And there's also at least on Chrome extension that works as an SSH client. But you are right, that Windows doesn't come (or didn't come?) with one out-of-the-box.
In any case, I can see that those addition things like rsync or PDF manipulation might differ between the different operating systems. I was really just talking about browser plus ssh (client).
