I have tried to remove system default (or inbox) drivers from an offline mounted image of Win 10 using DISM Remove-Driver command
e.g. Dism /Image C:\w10_dism\image /Remove-Driver /Driver:1394.inf

..but the utility doesn't allow me to do this, returns error 50: dism cant remove system default drivers
There's supposed to be a way to unflag the drivers as non-system drivers so that dism can execute the command successfully.
I am looking for a detailed walkthrough on how to achieve this.

i was doing some r&d with windows and found around 500 drivers that i am never going to use, so i thought of getting rid of those.. but i think you could unflag those drivers in the mounted image, this worked with win 7 and then use dism to clear them out - but i am no expert in dism, having used the utility only a couple of times
 
ok i figured this out with google's help..
you have to modify the Version key of the driver in image registry. The version key for default drivers starts with FF which has to be changed to 00 which removes the default flag from the driver
to modify keys, you have to first load the image registry (imgfolder/Windows/system32/config/DRIVERS) to host registry and edit it out from there
the version key is in binary format
after that the remove-driver command works successfully - now i would need a script to automate this
