XP Mode for Windows 7

To ease the application compatibility issues for migrating to Windows 7, Microsoft is going to incorporate the Virtual PC technology in to the Windows 7 operating system. The Windows XP applications will be published and run within the Windows 7 Desktop to achieve a seamless user experience. See the Windows team blog announcement here.

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.
