If a version of Virtual PC for Windows already exists on the host computer, you must uninstall it before you install Windows Virtual PC.

To install Windows Virtual PC

  2. Run the installation file on the host computer, and follow the steps in the wizard.

Windows Virtual PC includes the Integration Components package, which provides features that improve the interaction between the virtual environment and the physical computer. For example, it lets your mouse move between the host and the guest computers. MED-V requires the installation of the Integration Components package.

How to Install and Configure the Windows Virtual PC Update

The Microsoft update associated with article KB977206 enables Windows XP Mode for computers without hardware-assisted virtualization (HAV) technology. We recommended that you install this update because some integration features might not work correctly if the Integration Components package in the guest operating system do not match the version of Windows Virtual PC that is installed on the host computer.

You do not have to install this update when you are installing MED-V on host computers that are running Windows 7 with Service Pack 1.

In addition to the update listed here, we recommend that you review all available Windows Virtual PC updates and apply those updates that are appropriate or necessary for your environment.

  • *.VSV

  • *.VHD
