DOS was an IBM product, but the original Windows-type interface was a XEROX PARC invention.
Wikipedia says: "Xerox Palo Alto Research Center (PARC) was a flagship research division of the Xerox Corporation, based in Palo Alto, California, USA. It was founded in 1970, and spun out as a separate company (still wholly owned by Xerox) in 2002. It is best known for essentially creating the modern personal computer graphical user interface (GUI) paradigm."

Just wanted to mention that VMware Server is also free... and just as good as (better than?) MicroSoft Virtual Server.
