KMS38 Activation

Overview

  • How to use it? Please find the instructions here.

  • This activation method activates Windows 10/11 and Windows Server (14393 and later builds), until 19 January 2038 03:14:07 UTC.

  • This activation method does not store any files on the system.

  • This activation method works offline.

  • Unlike HWID and Online KMS activation option, KMS38 does not match with any official activation method.

  • Make sure the following things have been accounted for, before applying KMS38 Activation:

    • Before the activation, if any KMS activator is installed, then make sure to uninstall it completely.

    • After KMS38 activation has been achieved, if you want to use the 180 Days KMS Activator for MS Office, then you must make sure that it (the 180 Days KMS Activator for MS Office) is compatible with Windows KMS38 activation. FYI, the following activators are compatible and can activate Office without disrupting the Windows KMS38 activation.

      KMS_VL_ALL by abbodi1406

      MAS (Online KMS option)

  • Any KMS Activator which is not compatible with KMS38 may overwrite the KMS38 activation for Windows with its own 180 days activation, thereby destroying the KMS38 activation for Windows. To prevent this accidental overwriting, you can select the KMS38 protection option.

How does it work?

  • In a genuine KMS activation environment, activation lasts a maximum of up to 180 days. This is done using a valid license and server setup.

  • However, in the Windows major upgrade process, the system uses gatherosstate.exe to carry over the remaining KMS activation period. It does it by creating a ticket that can be used offline.

  • The trick is that we can fool the gatherosstate.exe about the remaining KMS activation period and manually put the desired period maximum up to 19 January 2038 03:14:07 UTC.

  • Why it's limited to the year 2038?
    It's related to the Y2K38 problem as this date (19 January 2038 03:14:07 UTC) is the maximum date we can give to gatherosstate.exe without it looping back to the year 1970.

Q: Can Microsoft block this kind of activation?
A: Not directly. They could only update Clipup to allow for a maximum activation period of 180 days. Not much besides that can be done on their part. The tickets are not sent to Microsoft at all, so they can't block them or take action directly.

Notes:

  • X86-X64 and ARM64 architecture systems are supported.

  • Any Evaluation version of Windows (i.e. 'EVAL' LTSB/C) cannot be activated.

  • KMS38 only supports Windows/server version 14393 (1607) and newer versions.

  • ServerRdsh edition does not officially support activation on non-azure systems.

KMS38 Protection

  • By default, KMS38 Activation is vulnerable to unintended replacement by a 180-Day KMS Activator.

  • If you are going to use KMS_VL_ALL by abbodi1406 or MAS (Online KMS option) for Office activation, then you don't need to enable this protection.

  • However, with a few tricks, you can ensure that no alternative KMS Activator can replace KMS38 Activation by accident or even on purpose. below is the explanation for how to do/undo that.

  • In the KMS activation method, Windows first checks the KMS IP registered as a specific KMS, and if that is not defined then it checks the Global KMS IP. Another fact is that if Localhost (IP range 127.0.0.0/8) is defined as KMS IP in Windows 8 and later OS then Windows will not accept it as a valid KMS IP. This script simply utilizes the above facts to protect the KMS38 activation from being overwritten by any alternative 'normal' 180-Day KMS Activation and at the same time that KMS activator can be used for Office activation.

  • Script steps-

    • Set the Windows edition-specific KMS IP to Localhost (127.0.0.2)

    • Lock the below Registry with reg_own snippet by AveYo

    • Done.

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform\55c92734-d682-4d71-983e-d6ec3f16059f\XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX\

Command line Switches

  • This is applicable only in separate file versions.

  • If any parameter is used then the script will automatically run in unattended mode.

  • To activate,

    "KMS38_Activation.cmd" /a

  • To activate along with KMS38 protection (from being replaced by 180 days KMS activation),

    "KMS38_Activation.cmd" /ap

  • To only generate GenuineTicket.xml,

    "KMS38_Activation.cmd" /g

  • To remove KMS38 protection,

    "KMS38_Activation.cmd" /x

File Details

Besides the plain batch script, KMS38 activation requires the use of an official gatherosstate.exe (x86) file.

     File: gatherosstate.exe
    SHA-1: FABB5A0FC1E6A372219711152291339AF36ED0B5

It's taken from Windows 10 Version 1607 ADK (Section: User State Migration Tool)

Further, in the case of Windows Server Core editions, the system doesn't have clipup.exe file. So to activate it, MAS separate files version contains the below file. (It's not included in MAS AIO)

      File: ClipUp.exe
     SHA-1: 48D928B1BEC25A56FE896C430C2C034B7866AA7A

It's taken from Windows Server 2016 x64 ISO

Manual Activation

  • You need the gatherosstate.exe file, get it from MAS separate files version.

  • Make a folder named Files in C drive, C:\Files and copy the gatherosstate.exe file in that folder.

  • Open Windows Powershell as administrator, and enter the following listed commands in the sequence in which they are given.

  • Enter the Key, (Replace <key> with the key from the above list) with the following command

slmgr /ipk <key>

  • Copy the below code all at once and enter in PowerShell to modify the gatherosstate.exe file.

  • A GenuineTicket.xml file should be created in the folder C:\Files\ now let's apply it.

clipup -v -o -altto C:\Files\

  • Check Activation Status with the following command:

slmgr /xpr

  • Done.
