Microsoft Hardware-Assisted Virtualization Detection Tool – Can my PC run Windows XP Mode ?
Windows Virtual PC (Windows XP Mode) requires processors capable of hardware-assisted virtualization with AMD-V, Intel VT or VIA VT turned on in the BIOS.
Windows XP Mode allows users of Windows 7 Professional (or higher) the ability to run Windows XP productivity applications that may not be compatible with Windows 7.
Check if your PC hardware works with Windows XP Mode by downloading and running Hardware-assisted virtualization (HAV) detection tool.
