+# \$OEM\$ Folders
+
+(Windows Pre-Activation)
+
+------------------------------------------------------------------------
+
+## Overview
+
+-   To create a pre-activated Windows installation .iso, do the following things:
+
+-   Extract `$OEM$` folder to 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 first internet contact.
+
+------------------------------------------------------------------------
+
+## Notes
+
+-   MAS AIO version doesn't contains `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.
+
+------------------------------------------------------------------------
+
+## 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.
+
+------------------------------------------------------------------------
+
+## 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 and Office both will be activated when connected to the internet for the first time. This option uses renewal task for lifetime activation.
+
+------------------------------------------------------------------------
+
