Select processors from Advanced Micro Devices do not support Windows 7 "XP mode" though, like Intel, the vast majority of shipping processors do support XP mode. Microsoft describes XP mode on its Web site as follows:
"As part of the upcoming Windows 7 Release Candidate milestone, Microsoft will release a beta version of Windows XP Mode, which allows users of Windows 7 Professional and above to launch many older Windows XP productivity applications directly from their Windows 7 desktop.
The Windows XP Mode stand-alone feature is specifically designed to help small businesses that are using Windows XP applications move to Windows 7. For larger businesses, Microsoft Enterprise Desktop Virtualization (MED-V) MED-V 2.0 builds on top of Windows Virtual PC and provides centralized management of Windows XP Mode. MED-V 2.0 will be available in beta within 90 days of general availability of Windows 7."
