For me, my first ever experience of fortune was on DEC VMS systems.

Many, many, moons ago Windows NT had support for an 'autoexec.nt' batch file which did the same, so it's not a new feature just horribly undocumented.
I use it to have a different prompt for administrator windows.
To anyone using it: Be careful. Any side effects in your autorun script can have entertaining effects on batch files when you least expect it.

TLDR is that for /f loops do spawn a child cmd.exe process and you won't like the result (recursiveness).
The common one I've seen surprisingly often is the autorun script doing "cd" and causing for /f loops to break in some way.
