July 23, 2025Win11 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

August 13, 2025What is the difference between RTM and KMS keys?
Not much for regular users. RTM keys are the standard generic ones. KMS keys are meant for companies running their own activation servers internally. Both behave the same when you're just installing Windows at home. The difference only matters to IT departments managing many machines.

Do free Windows 10/11 keys activate Windows permanently?
No. Generic keys let you install Windows and select your edition, but they don't provide permanent activation. To fully activate, you need a genuine retail key, OEM license, or volume license. The keys listed are installation keys only, published by Microsoft for IT and testing purposes.

Can I upgrade from Windows 10 to Windows 11 with generic keys?
No. You need activated Windows 10 or a genuine Windows 11 key to upgrade. Generic keys are only for fresh installs, and your PC still has to pass the TPM 2.0 and Secure Boot check or the upgrade won't proceed.

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?

If it is KMS and the KMS is not accessible, it will deactivate after like 6 months. There isn't really a such thing as volume keys anymore. The other type that are usually sold on the grey market are OEM, they'll keep selling the same key until it stops activating, then sell a new one. Problem is if you have to reactivate windows due to changing hardware, it will not reactivate down the road for that reason. KMS key can cause your system to get partially locked down, and they will see some info about you in the KMS server. They can deactivate your key any time (or like I said, it will expire eventually if it can't "phone home"). Technically, this shouldn't really be discussed in here anyway. It is up to you if you want to risk it or not.

Computers that are running volume licensing editions of Windows Server and Windows client are, by default, KMS clients with no extra configuration needed as the relevant GVLK is already there.

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.
