I'm not 100% sure when I started using putty, but I definitely used it in 2004. I still need a ssh client and terminal emulator for Windows. I still don't want to install a unix like environment just to have a terminal. I still don't want tabs in my terminal, lots of windows works just fine. I still need X11 forwarding so I can run programs on remote systems and display them on Windows (VcXsrv is an easier to get going X server than others I've used on Windows).

I might like to have something that can do whatever magic so I can gcloud and aws auth on my remote machine without cutting and pasting giant urls and auth blobs to and fro all the time; but I'm using a auth token that needs to stay connected to the windows machine. In a more integrated corp environment this would probably be keberos/active directory/magic?

Are there any better alternatives?

I still use putty because it does what I need for it to do. No need to change just because MS has their own terminals application, which besides I far from trust.
