To determine whether your PC supports hardware virtualization:

Step 1. Does my PC have a CPU with support for hardware virtualization?

Download and run the Hardware-Assisted Virtualization Detection Tool

If you receive the message This computer does not have hardware-assisted virtualization, your computer does not meet the hardware requirement for Windows Virtual PC, but you can still use Windows 7 XP Mode by running this hotfix. Be aware that XP Mode will run much better if hardware-assisted virtualization can be enabled.

If you receive the message Hardware-assisted virtualization is not enabled on this computer, go on to Step 2 below.

If you receive the message This computer is configured with hardware-assisted virtualization, download and install Windows Virtual PC and Windows XP Mode.

Step 2. Does my PC BIOS support hardware virtualization, and is it turned on?

Instructions to turn on hardware virtualization in your PC BIOS are specific to OEM models. It is important that after changing your BIOS settings the PC is completely shut down at the power switch before restarting so that the new BIOS settings can take place.

Examples for some models of some computer manufacturer's BIOS settings are below:

Sample instructions for your PC

Please note the instructions above may not work in all cases and consulting with your computer manufacturer may be necessary. Additionally, we expect hardware virtualization to become more available when Windows 7 is shipped, particularly in business-class PCs. For those PCs that come pre-installed with Windows XP Mode we recommend the computer manufacturer turn on hardware virtualization before shipping the PC.

Once you have confirmed your PC supports hardware virtualization
Download and install Windows Virtual PC and Windows XP Mode
