$OEM$ Folders

To create a pre-activated Windows installation .iso, do the following:

  • Extract the $OEM$ 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, 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 for activation method details and select the activation method as per your requirement.
warning

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 LTSC because the default installed key is OEM. You can work around this issue by using Non-IoT Windows 10 Enterprise LTSC ISO, in which case the HWID method in preactivation will use IoT LTSC key to change the edition.

Edit ISO File​

  • As stated above, you can copy the $OEM$ folder to your bootable USB so you don't have to edit the ISO file. However, if you need to, then follow the steps below.
  • Download AnyBurn Free Portable and extract this zip file
  • Run the file named AnyBurn(64-bit)\AnyBurn.exe
  • Select the option named Edit image file
  • Follow the on-screen instructions and add the $OEM$ folder to the sources folder so that the directory will appear like this: \sources\$OEM$
  • Save the ISO, that's it.

KMS38 - Server Cor/Acor​

  • Windows Server Cor/Acor (No GUI) editions don't have the clipup.exe file.
  • To KMS38 activate it, you need to download the missing ClipUp.exe file from this link.
    File: ClipUp.exe
    SHA-256: 0d6e9f6bbd0321eda149658d96040cb4f79e0bd93ba60061f25b28fecbf4d4ef
    This file has digital signatures that can be verified. You can also get this file from the official Windows Server 2016 x64 RTM ISO.
  • Put the ClipUp.exe beside the KMS38 Activation script. That would be either MAS_AIO.cmd or KMS38_Activation.cmd
  • The activation script will check ClipUp.exe in the current folder (from where script is running) and will use it accordingly.

HWID​

  • When using HWID activation, no files are stored on the system, and Windows 10-11 will be activated when connected to the internet for the first time.

  • If Office is preinstalled then Ohook method will activate the Office immediately without Internet. This activation uses custom sppc.dll file for the activation.
