KMS38 Activation
Discover KMS38 Activation – a secure, open-source solution for activating Windows and Office products.
KMS38 provides offline activation for Windows 10/11 and Server (build 14393+) with validity until 2038, without leaving any files on your system.
Learn how this clever method extends Microsoft's KMS technology for permanent offline activation.
Overview
- This activation method activates Windows 10/11 and Windows Server (14393 and later builds), until January 19, 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 options, KMS38 does not match with any official activation method.
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.
- In the Windows major upgrade process, the system uses
gatherosstate.exeto carry over the remaining KMS activation period. It does this by creating a ticket that can be used offline.
- In the Windows major upgrade process, the system uses
The trick is that we can fool the
gatherosstate.exeabout the remaining KMS activation period and manually put the desired period maximum up to January 19, 2038, 03:14:07 UTC.Why is it limited to the year 2038?
- This is due to the Y2K38 problem. This date (19 January 2038, 03:14:07 UTC) is the maximum value that can fit into a signed 32 bit integer.
How can we convince the gatherosstate.exe?
- There are two methods for it.
- 1- Place a custom slc.dll file beside gatherosstate.exe: gatherosstate.exe uses the system's
C:\Windows\System32\slc.dllfile to gather the system's info. If we place a custom slc.dll file beside gatherosstate.exe which can send the rubbish data to it, then it will simply accept it and generate a valid ticket allowing activation up to January 19, 2038, 03:14:07 UTC. - 2- Modify the gatherosstate.exe file itself so that it doesn't check the system's activation status and we can put the activation period as we wish.

Important
::: important To be Clear,
- we are not modifying/patching any on-board system file to get the ticket.
- Gatherosstate.exe is a part of the ISO file and not available in C drive system files. The system's slc.dll file is not touched; instead, we use custom slc.dll only for a brief moment of ticket generation.
- Latest MAS doesn't use any of these methods; instead, it uses ready-to-use Universal Tickets (check below for manual activation info).
- 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.

KMS38 - Server Cor/Acor
- Windows Server Cor/Acor (No GUI) editions don't have the
clipup.exefile. - To KMS38 activate it, you need to download the
ClipUp.exefile from this link app.box.com/s/.File: ClipUp.exeSHA-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.download. - Put the
ClipUp.exefile beside the KMS38 Activation script. That would be eitherMAS_AIO.cmdorKMS38_Activation.cmd
The activation script will check forClipUp.exein the current folder (from where the script is running) and will use it accordingly.
KMS38 Protection
KMS38 Activation is vulnerable to unintended replacement by a 180-Day KMS Activator.
From MAS 1.7, the script will enable KMS38 protection by default.
If you are going to use KMS_VL_ALL by abbodi1406 or AEG (Online KMS option) for Office activation, then you can choose to remove this protection.
Below is the explanation for how the script protect KMS38.
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 the 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)
- Protect the below Registry from edit and delete
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform\55c92734-d682-4d71-983e-d6ec3f16059f\XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX\
