How to add Registry keys via DISM in Windows

In this video, I will show you how to service or modify the Windows Registry on an offline image. I will be using a Windows 11 ISO image file in this example, but the technique is the same whether you use a Windows 10 ISO image.



Commands:
Dism /Get-WimInfo /WimFile:C:\ISO\Sources\install.wim
Dism /Mount-Wim /WimFile:C:\ISO\Sources\install.wim /index:6 /MountDir:C:\Mount
reg load HKLM\OFFLINE C:\Mount\Windows\System32\Config\Hardware
reg unload HKLM\OFFLINE
Dism /Unmount-Image /MountDir:C:\mount /Commit
