With Parallels in the news so much on the Mac side, some people might have seen this coming. Microsoft has made Virtual PC available as a free download, which is a real boon to folks that are beta testing Vista, Office and the like. Head on over the Microsoft Virtual PC home page for details and links on the free Virtual PC 2004 SP 1 download, which includes support for Vista installations. This is a great way to test different Operating System versions, environmental changes or other beta software without hosing up your current setup.
