DPInst
DPInst is a tool that allows us to install signed Plug and Play (PnP) function drivers, as well as signed class filter drivers. It can also run in legacy mode, to install unsigned drivers. Starting with Windows 7, DPInst is part of the WDK (Windows Driver Kit).
DPInst can be run interactively or silently. DPInst tries to install the driver packages that can be found in the working directory. Both scenarios (interactive or silent) accept the use of a XML file that will contain the configuration flags.
