1).       Registries for services:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\rvd\*

Most important information is under:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\rvd\Parameters

2).       Registry for application path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\rvd.exe

    To pre-pend information to the PATH environment variable on a per-application, per-process basis.
