Mount without Virtual PC or Microsoft Virtual Server
If you also use Windows XP on another computer, you can transfer that VHD file to the XP computer and mount it without having to run Virtual PC or Microsoft Virtual Server. You can install only a component of Microsoft Virtual Server and run a command from the command line.
NOTE: If you have applied a password to your VHD file using BitLocker in Windows 7, you CANNOT access your VHD file in Windows XP. You will be asked to format the drive.

In Windows Explorer, navigate to the C:\Program Files\Microsoft Virtual Server directory. In the right pane, hold down the Shift key while right-clicking on the Vhdmount directory. Select Open Command Line Here from the pop-up menu.
At the command prompt, enter the following line.

Replace “<path to VHD file>” with the location of the VHD file you want to attach. Press Enter. You should see a message indicating the Virtual Hard Disk was successfully plugged in.

Again, replace “<path to VHD file>” with the location of your VHD file.
If you still have Windows Explorer open and your VHD selected, you will receive an error when you try to detach the VHD file. You must either select a different drive, or close Windows Explorer.
Once the VHD file is no longer being used, you can enter the detach command again and you should see a message indicating that the virtual hard disk has been successfully unplugged.
This component of Microsoft Virtual Server is useful if you transfer files between a Windows 7 computer and a Windows XP computer. You can keep all your files in one portable file and easily access them on both operating systems.
