Comments

The value name and value are written to the registry path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DriverName\Parameters, where DriverName is the driver name specified as input to VC_OpenProfileAccess.

If the \Parameters subkey does not exist, it is created. If the specified value name does not exist under the \Parameters subkey, it is created.

To read values from a driver’s \Parameters registry key, call VC_ReadProfile.
