Default Behavior

The Parvdm service is a kernel device driver. In Windows 8 it is starting automatically during the operating system startup. If Parvdm fails to load or initialize, Windows 8 startup proceeds. The error details should be added to Event Log without notifying the user.

Dependencies

Parvdm can't start, if the Parallel port driver service is disabled or not available.

Restore Default Startup Configuration for Parvdm

Before you begin doing this, make sure that all the services on which Parvdm depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the commands below, paste them into the command window and press ENTER:

sc config Parvdm start= auto
sc start Parvdm

3. Close the command window and restart the computer.

The Parvdm service is using the parvdm.sys file that is located in the %WinDir%\System32\drivers folder. If the file is corrupted or deleted, you can put it back in there.
