Hotfix integration I do - these: 3074678, 3074686, kb3081441, kb3081444 U need the latest ADK (msdn.microsoft.com/en-us/windows/hardware/dn913721.aspx -sry, not allowed to post links ), and run DISM from its folder (provided your iso is extracted to D:\Win10 and your updates downloaded to d:\updates): cd C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\amd64\DISM dism /mount-wim /wimfile D:\Win10\sources\install.wim /mountdir D:\wim /index:1 dism /image D:\wim /Add-Package /PackagePath D:\updates dism /Unmount-Wim /MountDir D:\wim /commit
