One of the coolest features of Windows 7 is “XP Mode”, a way to run a virtual Windows XP session in Windows 7.
At its most basic, XP Mode offers “Desktop Mode”, in which a virtual machine opens up and boots into its OS. This is nice, but it’s nothing extraordinary – in fact, users of Virtual PC 2007, VMWare Workstation and Sun’s VirtualBox will probably yawn and wonder what all the fuss is about. After all, it’s not much different than running any of those apps.
Where XP Mode really shines is “Seamless Mode”, in which shortcuts for applications installed on the virtual machine are added to the Windows 7 start menu. When you want to run one of those apps, you don’t have to start the virtual machine in desktop mode and wait for it to boot up – the application runs within a window under Windows 7. Aside from the “(Remote)” tag added to the title bar of the application, you’d have no idea it was even running virtually! Cool, huh? So you can now finally run Office 2007 and a virtualized Office 2003 on the same machine!
