ETA: I wouldn''t recommend running Virtual Windows on your Mac unless you absolutely have to. The reason being is that Mac is (almost) immune to viruses at this point in time. Adding the Virtual PC to your computer will open the opportunity for viruses to enter your computer. Why run that risk if you don''t have to?
