Virtual PC Application Services Service Failed

When I look at my Windows XP Pro event viewer there's one service that fails everytime I log in:

Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7000
Date: 1/1/2005
Time: 7:49:01 PM
User: N/A
Description:
The Virtual PC Application Services service failed to start due to the following error:
The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.

For more information, see Help and Support Center at »go.microsoft.com/fwlink/events.asp.

I looked on google and couldn't find information on the Virutal PC Application Service.

What is this service? How do I start it back up or totally remove it from starting up?
