DOS is but Windows isn't. (although support in early Windows was
a bit half hearted!). However even in DOS there were things called
TSRs that gave the illusion of running in the background, but they
are a wee bit tricky to write. But if you use DR DOS(Or Novell DOS)
that had full pre-emptive multi tasking and you could run multiple
Windows 9x also runs things preemptively but the implementation is
a wee bit flaky, Windows NT/2K/XP all do much better.

Unix is multi tasking from the ground up. To run a command in the
background just put an ampersand at the end of the command.
