Windows 7 To Include "Windows XP Mode"

Z80xxc! writes "Paul Thurrott's WinSuperSite reports that Windows 7 will include a built-in virtual machine with a fully licensed copy of Windows XP Professional SP3. The VM runs in a modified version of Virtual PC, and applications running in the VM can interact directly with the host operating system as if they were running on the Windows 7 installation itself. While details are scarce for now, it looks as if this feature will only be available as a (free) addon for Professional, Enterprise and Ultimate editions of Windows 7. Also, a processor supporting hardware virtualization will be required, indicating that this is perhaps aimed more at power users and corporate users, rather than consumers. Microsoft confirmed the feature last night."

      The benefit of which was that you did not take nearly the performance hit you would for virtualizing the entire computer a'la a traditional VM, but the downside was that Classic would no longer work once Macs made the switch to Intel architectures because you weren't virtualizing hardware at all, just abstracting the system APIs into newer calls.
