I have been reading that injecting the drivers via dism increases the size of the image (it is no very important), the problem i have seen, after the system is installed, all the drivers are stored in the folder "C:\Windows\System32\DriverStore\FileRepository" regardless if they are needed or not, so it increases the size of the windows installed.

Also i have been reading that installing drivers from dvd or usb flash media, do the same as it copies all the drivers founded in the path of drivers.

Also i have read that it can add drivers via DPinst TechNet link, so only the drivers needed are copied to the folder DriverStore.

And my question please, what is the best method to add the drivers? i am looking for a method like the windows xp (it does not store all the drivers after the setup is finished)
