@KYHI, would the "WIN81SEx86" mentioned in your signature be a smaller download for tropicalpaddy than the full WinPE download in the ADK? Does it have the version of DISM which would work with /add-drivers in Windows 10?
Yes it is smaller in size, does contain a windows type interface and will add drivers to the offline image using dism..
the 8.1 ADK download is 3GB and then you have to work within a command prompt..
SE is like 500MB and you work within a limited windows GUI
Actually the best method would be to mount the install.wim and add-drivers to it and to the WinRE.wim, before installation..
Although I've not tested the windows installer using a modified install.wim (install.wim with drivers added)
the windows installer may reject the wim..
But can always
Apply the modified install.wim
In Case, somebody wants to test the windows installer by replacing the install.wim with a modified install wim..
Here is a script that will run the modifications you need..
It will look for the mounted setup media (edition and arch of target pc)
it will look for the Drivers folder within it's own directory (export "drivers" folder, copied into current directory)
It will ask for the product key (generic or activation)
then you just replace MS install.wim with the modified Install.wim
If installer accepts the modified install.wim, your system will be installed with the needed drivers pre-loaded
