$OEM$ 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 from the OEM channel, except for Enterprise editions and Windows Server operating systems.
  • However, in Windows 10, IoT Enterprise editions were not included in the Enterprise category list during the installation process. As a result, Enterprise with an OEM key can handle setupcomplete.cmd, but IoT Enterprise (LTSC) cannot. This was fixed in later Windows 11 versions.
  • In Windows 10 IoT Enterprise (LTSC), you can resolve this issue by using the Non-IoT Windows 10 Enterprise LTSC ISO. In this case, the HWID method in preactivation will install the IoT LTSC key to change the edition and enable HWID activation.
  • In Windows 11 IoT Enterprise (LTSC), it works fine as expected by default.

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.

Ohook​

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

KMS38​

  • When using KMS38 activation, no files are stored on the system, and Windows 10-11-Server becomes activated immediately without Internet.

Online KMS​

  • When using Online KMS activation, Windows-Server and Office (Preinstalled) both will be activated when connected to the internet for the first time. This option uses a renewal task for lifetime activation.
