# \$OEM\$ Folders

(Windows Pre-Activation)

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

## Overview

-   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.

## Notes

-   MAS AIO version doesn't contain `clipup.exe` file, if you need to activate `Server Core/Acor` editions then please use MAS separate files version.

-   You can check [here](https://massgrave.dev/) about activation method details and select the activation method as per your requirement.
