OK i have Fully tested this DPsXtrct-0.1.zip on diffrent setups now pc,vmware,laptop and it works perfect 100% no problems if you choose 1, all or any of the packs
1 small bug i have found is if you install driverpacks using the option to start the driverpack finisher on guirunonce or runonce and select/highlight no drivers in DPXtract and just close the DPXtract. at the end of the install you get a "windows cannot find DPsFnshr.exe" this is because i am sure you know this. when you install driverpacks it mods your WINNT.SIF and adds this:
command9="%SystemDrive%\DPsFnshr.exe"
so you would need to remove this command if no drivers are selected (i am sure theres an easy fix)
i really cant thank you enough Kal for making this, it is so easy to use, like you say "drop the files into oem folder, replace presetup.cmd and edit the ini to suit your needs", the ini is very simple and easy to understand and is fully setup ready for the latest driverpacks without any editing, and as you said it does work with 3rd party driverpacks i only had to edit the ini file took around 1 min and it all worked how it should, i really like it being on a 1min timer so its unattended if needed or with a click of the mouse or keyboard the timer stops and you can select what you need... perfect..
a "keep drivers" option would be nice like you said but is really not essential for me.
i think it would be a great idea if the driverpacks guys could include some kinda option when installing driverpacks just like
Option
Select how to unpack drivers
. Automattic
. Using DriverPack Xtract
and the modded presetup.cmd could get auto copied to the right folder
maybe you guys could expand on this idea and get an it to generate the ini file needed by DPXtract
really nice work anyways for ver0.1 
i think this will halp a lot of people out and saved me hours of work
