Coyote Moon, Inc. Apple Macs iPad Tweet Share Email Parallels lets you run many different types of operating systems on your Mac. Because the developers knew that most Mac users will want to install at least a Windows OS, Parallels includes a Windows Express installation option that eliminates the need to babysit a Windows XP or Vista installation.

This option creates a virtual machine with settings that will work just fine for most individuals. You can always customize the virtual machine parameters later if you need to. The real advantage of Windows Express is that it's fast and easy; it does most of the work for you. It will collect most of the information that Windows needs by asking you some questions. Once you supply the answers, you can leave and then return to a fully installed version of Windows. This is a much more pleasant Windows installation than the standard. The downside is that the Windows Express method doesn't let you directly configure many settings, including type of network, memory, disk space, and other parameters, although you can always tweak these and other settings later.
