... Hilariously, I think shell might actually win that; neither is installed by default, but you get some sort of bash/sh with any of interix, WSL1/2, git, cygwin, or mingw.
isn't WSL like a hypervisor that runs a guest? I'm clueless about Windows but when I start a WSL it is usually some form of Debian or Ubuntu that I can download from the Microsoft "store". Therefore isn't the shell you have whatever comes with that guest?
