The Parallel port driver service failed to start

After migrating virtual machines from Virtual Server 2005 to Hyper-V, the following error message was prompted during start-up:

In the system event log the following event is logged:
Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7000
The Parallel port driver 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.

Same event is logged after P2V migration of servers, in my case it was Windows Server 2003.
In order to prevent this error from showing, I have disabled Parport service from registry, by setting the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Parport\Start to 4.
The following values for Start parameter are possible:
2Automatic. This is the default setting.
