It doesn't, much. There are two command line interpreters in NT-based
OSs, Command.com and Cmd.exe, and there are circumstances that can
flip either of these from LFN mode to 8.3 mode when Windows is the
underlying kernel (Command.com is always LFN-unaware when DOS mode,
i.e. IO.SYS, is the underlying kernel).

Raymond Chen blogged about this effect once; some concerted
Googling... er, searching... may find the relevant blog post. As I
recall, it happens after some 8.3-unaware program is used in the
course of that DOS console session; thereafter, all Prompt, Dir
listings etc. are in raw 8.3 for the life of that session.
