# \$OEM\$ Folders

(Windows Pre-Activation)

------------------------------------------------------------------------

## Overview

-   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](index.html) for activation method details and select the activation method as per your requirement.

------------------------------------------------------------------------

## 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](https://www.anyburn.com/anyburn.zip) 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.

------------------------------------------------------------------------

## Limitations

-   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 installed key is of the OEM channel.

-   The **solution** for this issue is to use (Non-Iot) Windows 10 Enterprise LTSC ISO, and the HWID method in preactivation will use Iot LTSC key to change the edition.

------------------------------------------------------------------------

## 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](files\ClipUp.zip).\
    \
    `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](https://download.microsoft.com/download/1/6/F/16FA20E6-4662-482A-920B-1A45CF5AAE3C/14393.0.160715-1616.RS1_RELEASE_SERVER_EVAL_X64FRE_EN-US.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.
