Some times you can not run your workstation on linux for different reasons.
I am more and more unhappy with "putty" I currently use.
Why isn't there a actively maintained SSH Terminal Client for Windows?
Please list SSH Terminal Client for Windows you like!
If you grab the official git windows client you get a mini-install with openssh which works fine :)
I use putty myself, and if I'm only allowed to use a web browser, I'll just log into chrome and use the ssh client chrome extension (which seems to be still in beta a year later)
You have the added benefit of having a bash command line (or zsh or whatever) to use as you like.
But for your question, cygwin plus openssh is an excellent solution. Try it.
