MAS is a well-known Microsoft product activation solution.

Now they announce in their discord.

Hi @everyone <:blobcatcozy:1118204792750231603> 

We’re thrilled to share some groundbreaking news from the <@&1139034750405853194> team!

Our team has successfully cracked almost the entire Windows / Office software licensing protection. With this new method, we can **permanently activate** almost **any version of Windows and Office**, spanning from **Vista to the latest Windows 11 and Server 2025 including CSVLK and ESU**.

We can easily activate Windows 10 ESU (Extended Security Updates) licenses, ensuring extended updates post-October 2025.

This breakthrough is even more impressive due to its simplicity—**no third-party file installation, no system file modifications, and completely clean execution**.

**This is the largest breakthrough in Windows / Office piracy ever.**

This solution will be available in the coming months—stay tuned for updates!

It's great，because it is no need to mod system file or install other thing.

How do they do it?

The product key is generated by Pkey2005?

How to generate legitimate activation information for registration on MS server.

Leaked private keys?

The pkeytool, it could check the validity of the key and the number of times the key is available.

It was released to public:

In this blogpost, we introduce TSforge, one of our most powerful activation exploits ever. Capable of activating every edition of every version of Windows since Windows 7, as well as every Windows addon and Office version since Office 2013, TSforge is both the most complex and most wide-reaching exploit we've implemented ...

1. Please don't use huge letters when you have something to say.
2. Can you prove your allegation regarding "send your genuine key to that Chinese server" ? Checking the validity of key is an offline process. Verifying the number of remaining activation for MAK (Multiple Activation Key) is made against Microsoft servers itself and not any other obscure server.
3. You have access to the source code. Please show us the guilty lines of code responsible with that accusation. Can you?

**MAS 3.3 ** ������

**The Empire Strikes Back**
### **TSforge:**
- In Windows 11 build 27802, Microsoft introduced a bug that causes Confirmation ID cache validation to always fail, forcing validation directly from the stored Confirmation ID each time the license status is checked.
- To circumvent this bug, TSforge is used to set the current Installation ID to that of a known key that can be used to generate valid Confirmation IDs.
- For more information on StaticCID, check https://massgrave.dev/tsforge#staticcid
- From now on, the script will use StaticCID method (requires Internet) on build 19041 and later.
- KMS4k activation option is now added in the script.
- Thanks a lot to <@370676311653482497> for working on this.
### **Change Office Edition:**
- Added the option to switch the Office update channel between VL and non-VL.
### **All:**
- Various other fixes and improvements.

I think it is a good guess that this is not some accidental "bug" introduced by Microsoft, but something done deliberately in order to break this type of activation.

It should also be noted that this "bug" does not only exist in some future "beta preview" version which most people will likely never install anyways, but has already been rolled out on all up to date Windows 11, Server 2022 and Server 2025 systems.

Maybe, now the MAS 3.4 RELEASE

RIP KMS38 (Oct 5,2018-Oct 28,2025)

https://massgrave.dev/kms38

Beginning with build 26100.7019, Microsoft fully deprecated this functionality, causing KMS38 to stop working on that build and all later versions.

KMS38 has now been removed from the MAS script. Users are advised to use HWID or TSforge activation instead.

If you still wish to use it on older Windows versions or keep it for archival purposes, you can download the script from here
