Windows 7 XP Mode Not Supported by All Processors

In trying to convince users to switch from XP to Windows 7 as soon as possible, Microsoft has recently announced that the operating system will come with an XP Mode add-on (provided free of charge for Windows 7 Professional, Windows Enterprise, and Windows Ultimate). While it is true that Windows XP Mode provides a viable means of running older productivity apps on a PC running Windows 7, it is also true that not all processors will be able to handle this task.

“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” explained Director of Windows Enterprise and Virtualization Strategy, Scott Woodgate, at the time.

Windows Virtual PC requires hardware-assisted virtualization technology (VT) support, meaning that not all processors will be able to handle it. Take Intel processors for example; according to ZDNet’s Ed Bott, not all will be able to support Windows Virtual PC:

One simple way to check if a processor will be able to support Windows Virtual PC and will be able to run Windows XP Mode, is to look at the name. If the name has VT (virtualization technology) in it, then you should be ok; in Intel’s case you should see Intel VT, while in AMD’s case it is AMD-V. An even simpler method is by using specialized software – SecurAble for example comes free of charge, requires no installation, and will inform you if your CPU supports hardware virtualization.
