Win11 keeps trying to use KMS activation and won't let me Activate via AAD even on clean builds
Did you already join them to Entra so they can activate? What does dsregcmd /status show? If tegistered, try running slmgr /ato to force it. Do they have the correct licensing assigned in the admin portal? The iso you're using, is it indeed not a volume licensing image? Had also before when undoing an AD joined machine I had to go and reset the Windows install via settings and do a clean cloud install instead of local for it to activate properly later on. This is if i read your post correctly. More on reddit.com

Windows 10 & 11 Product Keys — All Editions, Generic & KMS (2026)
March 16, 2026 - KMS client keys are for corporate environments where a KMS host server manages activation across the network. KMS keys will NOT work on a standalone home computer without a KMS server. Yes. Windows 10 and 11 work fully without activation — you get all updates, security patches, and can install any application.

r/techsupport on Reddit: What are the risks of using a volume or kms windows 11 key
July 11, 2025 -

I bought a cheap ($11) windows 11 key on amazon, the seller seemed trustworthy since the vast majority of the reviews were good and the 100+ comments were all saying that it work, and since this is on Amazon, i don't belive this reviews are fake (also, it had a thousand sales last month according to amazon)

I received the key via email a few hours later.

But i not fully confident, i know this key is very likely not ''legal'', so i did a little bit of research and, for what i find out, there are 3 types of license: Retail, OEM and Volume/KMS (not sure Volume and KMS are the exact same thing or not)

What are the risks of using this key if it is Volume/KMS?

I saw people saying it will send data about my pc, account, and even network information to the supposed "organization" this license was supposed to be. Some people say not to worry, will not send any important information.

I saw answers saying it will not even activate if it is Volume/KMS, since the pc would have to be connected to the "organization" network, or something like that...

I may ended up not even using this key.

Could someone help me out?

r/VMwareHorizon on Reddit: How to activate KMS windows 11 for Instant Clone pools (Persistent and non persistent)?
February 22, 2024 -

Hi

As a newbie on Horizon View 8, I've manage to create pool of Instant clone desktops with Win11. Actually I must create twoo pools (a non persistent pool and a persistent).

So in order to create a Golden Image for testing purpose:

  • I have created a Win11

  • I've joined it to domain

  • I've installed som applications

  • I've installed the DEM agent

  • I've installed the horizon Agent

  • I've applied the VMware Desktop Optimizer tool

If the previous steps are correct then I must step into the Win license activation process.

So according with the following link, I'm suposed to remove the native Windows11 license that cames on a fresh install and then install on it the win11 KMS license:

  1. Acquire a KMS license key.

  2. Invoke a script to remove the existing license. For more information, see the Microsoft Windows documentation to remove the Windows license key using a command.

  3. Restart Windows.

  4. Invoke a script that uses KMS licensing to activate Windows.

KMS treats each activated clone as a computer with a newly issued license.

Which script should I use at the step2 of the previous list???

Which script should I use at the step4 from the previous list???

Apart from that I have installed the KMS role on the DEM server to use it as KMS license server activator. On the server side I've ran the KMS wizzard to activated the KMS license for win11 and I'm now stucked cause I don't know which GPO should I set on the Desktop or Instant Clones OU to allow an automatic activation of the Win11 desktops of the pool.

Please help!!

Thanks in advance

Microsoft axes popular free Windows 11/10 KMS activation hack that worked without internet - Neowin
November 13, 2025 - That is because the company has removed a popular offline Windows 11 and 10 hack that was used to illegally activate systems. The method was dubbed KMS38 and was provided by MASSGRAVE. If you are not familiar, MASSGRAVE (where MAS stands for Microsoft Activation Scripts) is a project that offers various unofficial Windows and Office activation services. KMS38 was an offline activation method that worked by tricking the GatherOSstate EXE file so as to extend the KMS (Key Management Service) activation period up to January 19, 2038, 03:14:07 UTC, instead of the usual 180 days.
