Every version of MS-DOS came with EDLIN.
Every 16-bit version of Windows let you run EDLIN via the underlying MS-DOS.
Every 32-bit version of Windows from the first RTM of Windows 95 right through to the current version of Windows 10 came with EDLIN.
I also forgot FreeDOS wrote their own EDLIN port: https://github.com/FDOS/edlin
And on SourceForge, which is newer?? FreeDOS edlin: https://sourceforge.net/projects/freedos-edlin/
It's only 64-bit versions of (x86) Windows that don't come with EDLIN installed.
Also, in Vista, 7, 8, 8.1, & 10, you need to install NTVDM separately in order to run EDLIN. Typing the command for the first time brings up a Windows Troubleshooter Wizard to do just that for you.
