Thanks. I need to ask you some more questions, however: - do I really need to find (how?) the correct order to insert the KB patches? Isn't by number ok? - are there detailed info about the "Tweaks"? - do you know how could I slipstream USB3.0 drivers for Win7 on Skylake? - please reply with the "Quote" button, bacause the "@" doesn't send any notification - No special order needed for KBs, except RunOnce updates and those marked as "z" in my list (need to be integrated in Silent installs + SFX section, because they are not integrable or need to be placed after some KBs). Normally Wintoolkit automatically detects prerequisite KBs, so you can integrate them in one shot. - For the tweaks, have a look on the Wintoolkit forum section - For the USB 3.0 drivers you have 2 possibilities : 1- use the tool provided by your manufacturer to integrate them in your updated ISO, or 2- integrate them in the driver section of Wintoolkit (I never used this section, so please check if it's able to integrate them in boot.win).
