Since Windows 10 1709 Microsoft offers an optional SSH client feature. This is pretty sweet and much needed. Unfortunately, the current [as of writing this post] version 0.0.1.0 that you can install via the Features panel or the command line lacks some neat features like VT mouse support.
I can already hear the sneering from some people. Hey, sometimes I love me a simple click instead of remembering some keybindings across different applications. I am getting old and forgetful! So let’s give this old man some mouse support for his Windows OpenSSH.
Thankfully the OpenSSH version Microsoft offers via the optional feature is nothing special. You can simply go to Microsoft’s GitHub project for OpenSSH on Windows and download a newer release.
In fact, you do not even need to explicitly uninstall the existing feature, since it’s home directory is added to the PATH environment variable (C:\Windows\system32\OpenSSH), so you can simply unpack a freshly downloaded zip archive with a newer version of OpenSSH, extract it a location of your convenience and add that location higher in the PATH hierarchy.
And just like that you can have your mouse support, so you can pull things around in tmux.
