Git for Windows (referenced from https://git-scm.com/downloads/win) provides a BASH emulation, used to run Git from the command line. Some of the external commands, like ls, vi, nano and perl (currently v5.38.2), are provided, others, like ed, mkfs 😉, or gcc, aren't, but you can call Windows programs just like from CMD.EXE. This is, of course, also an emulation, but one that you possibly might have installed anyway.
