dism

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...

Right now we install Windows and then we install all the drivers and utilities from the motherboard manufacturer. Each one separately. What I'd really like to see is a utility that automatically slipstreams all the drivers and utilities into the Windows ISO. Yes, I know I can already do this...
