Microsoft's Virtual PC allows you to create virtual computers on your own Windows desktop. Each of these computers has all the hardware of a physical computer, enabling you to run each virtual PC as if it run on a dedicated machine. Virtual PC lets you run many operating systems at once on a single computer.
Virtual PC is an ideal tool if you need to use it for technical support, training or running multiple operating systems on one computer. The main program window and virtual machine console use a simple and user friendly GUI, making it easy to use. Better still, the program won't overuse your processor and leaves a very small memory footprint. You can even have a different IP address for each of your virtual machines.
You'll more than likely be surprised at the minimal GUI window and the mere handful of options when you first open Microsoft's Virtual PC application. But its strength is in its simplicity, which makes creating a virtual machine fast and easy. It even supports virtual floppy disks in the machines you create and does all its work without impairing the host machine's efficiency or performance. A wizard will take you step by step through the creation procedure so it's pretty hard to make any mistakes.
Virtual PC also has virtual machines already prepared if you want to make use of them. You can install guest operating systems to see how they run before putting them on your own hard drive or run different systems on each of the machines. This is very useful for diagnostics and troubleshooting and a real advantage to IT personnel.
