The documentation doesn't make this entirely clear, but I think these are two separate things: the original `edit` command which is built into Windows 11 (and has been built into prior Windows releases), and a replacement written in Rust that can optionally be installed.
Note that my link is dated 2023, whereas Wikipedia says that Microsoft Edit was first released in 2025: https://en.wikipedia.org/wiki/MS-DOS_Editor
The old EDIT never shipped with any 64-bit Windows IIRC, since it was a 16-bit MS-DOS application. I believe 32-bit Windows 10 has it..?
As someone who (mercifully) only occasionally has to touch Windows machines, I keep forgetting this, and then when I try to do stuff I’m flabbergasted that the operating system does not include a terminal text editor. (In a fit of pure desperation I even typed EDLIN into the Command Prompt — no go ;)
That was the case with Win11 about a year ago; if they finally started shipping EDIT64 then hey, that’s one positive recent change in Windows I suppose.
