Windows XP Mode is specifically designed to help small businesses move to Windows 7. Windows XP Mode provides you with the flexibility to run many older productivity applications on a Windows 7 based PC.
All you need to do is to install suitable applications directly in Windows XP Mode which is a virtual Windows XP environment running under Windows Virtual PC. The applications will be published to the Windows 7 desktop and then you can run them directly from Windows 7.
Windows XP Mode and Windows Virtual PC are best experienced on your new Windows 7 PC. We will be soon releasing the beta of Windows XP Mode and Windows Virtual PC for Windows 7 Professional and Windows 7 Ultimate.
这个不错，大家可以放心的升级成Windows7了
