Cannot install VM additions for Windows 2000 on Microsoft Virtual PC 7

Symptom Brief Description:
You cannot install the VM additions, which provide mouse and video drivers, on a Windows 2000 guest on Microsoft Virtual PC 7 running on the Windows 7 RC.
Problem:
Installation of the integration features or components, which were previously known as virtual machine additions fails on a Windows 2000 guest. Microsoft has dropped support for these older operating systems within Microsoft Virtual PC 7.
Symptom:

• Installation of the integration features fails.
• Video resolution is incorrect
• Mouse does not release from screen

Solution:
Copy the VMadditions.iso file from an installation of Microsoft Virtual PC 2007 SP1 running on a Windows XP computer. The default file location is C:\Program Files\Microsoft Virtual PC\Virtual Machine Additions\VMadditions.iso. Place the file on your Windows 7 machine with the newer additions at C:\Program Files\Windows Virtual PC\Integration Components (by default). You can than manually attach the ISO image to a virtual machine running Windows 2000 and install the additions.
This solution supplies video and mouse drivers within the guest, but sound does not function.
