(Windows Pre-Activation)
To create a pre-activated Windows installation .iso, do the following things:
Extract $OEM$ folder to the desktop using the MAS
script.
Copy the $OEM$ folder to the sources
folder in the Windows installation media (.iso or USB).
The directory will appear like this: \sources\$OEM$
in your altered .iso or on your bootable USB drive.
Now use this .iso or bootable USB drive to install Windows and it will either already be activated (KMS38) as soon as it boots or will self-activate (HWID or Online KMS) at the first internet contact.
You can check here about activation method details and select the activation method as per your requirement.
On Windows 8 and later, running setupcomplete.cmd is disabled if the default installed key for the edition is OEM Channel. For example - Preactivation won’t work for Windows 10 Iot Enterprise because installed key is of OEM channel.
Windows Server Cor/Acor (No GUI) editions don’t have
clipup.exe file.
To KMS38 activate it, you need to download
ClipUp.exe file from the below official MS link.
https://msdl.microsoft.com/download/symbols/clipup.exe/5789984414b000/clipup.exe
Rename the downloaded file as ClipUp.exe and put it
beside the KMS38 Activation script. That would be either
MAS_AIO.cmd or KMS38_Activation.cmd
Activation script will check ClipUp.exe in the
current folder (from where script is running) and will use it
accordingly.
