Is MAS safe?
-
How can I know if there is any malware?
MAS is fully open-source, with over 140K stars on GitHub and millions of users worldwide. You can open the batch files in Notepad to review the code yourself, or ask ChatGPT for help if you don’t understand something in the scripts.
You can also perform the activation manually, see this page for instructions. -
Will I receive updates? How is it different from an official license?
MAS does not interfere with Windows or Office updates. It functions in the same way as official licensing methods.
-
Will Microsoft ban my account if I use MAS?
No. Windows and Office piracy has existed for decades, and Microsoft has never banned accounts solely for this reason.
-
Is it legal? Can I face any consequences?
- By using MAS, you are bypassing official licensing methods and not paying Microsoft, so technically it is not legal.
- Is it safe?
- Home users: Yes, it's safe. Piracy has existed for decades, and Microsoft does not take action against individuals who pirate Windows or Office. Pursuing a home user over a $100–$200 license costs more in legal fees than it would recover and risks bad publicity. At most, you may see notifications that your license is not genuine (with MAS, these notifications do not appear).
- Businesses: We do not recommend that businesses use MAS. Microsoft conducts audits on business entities to verify licenses. While small businesses might be less likely to face audits, the risk is still yours. If you work in IT at a college or university, consult experienced senior staff about the chances of Microsoft audits at your institution.
How to remove MAS?
MAS uses different activation methods, see the link below for removal instructions for each one.
HWID, Ohook, TSforge, KMS38, Online KMS
How to change the Windows edition from Home to Pro?

No.
I changed my Windows edition from Home to Pro and now Windows is deactivated.

Can I link my Microsoft account safely with MAS activation methods?
Yes.
Can I update Windows/Office after activation?
Yes.
I'm in Russia and Office is not downloading.
Check this guide.
Can I activate Office 365?
Yes, use the Ohook activation option. However, you can't get server-side O365-specific features such as 1TB storage in OneDrive, though almost all other features and 5GB storage in a free OneDrive account would work fine.
Some features require signing in with a Microsoft account (free) in the Office apps.
Can I get the Copilot feature in Office with MAS activation?
No. Copilot is an additional plan that can be added to existing subscriptions of Microsoft 365.
Can I get Python in Excel with MAS activation?
No. Python in Excel is a server-side feature. To get this, you need to have a Microsoft 365 subscription.
Can I delete the MAS folder after activation?
Yes.
Does MAS work for Windows Vista/7/8.1?
Yes, TSforge, Ohook, and online KMS options work on Windows Vista/7/8.1.
How can I donate or contribute to the project?
The MASSGRAVE project doesn't accept donations and it's free.
It's because it's a community project and involves many contributors, splitting donations is not practical, and also because profiting from piracy is not good.
However, if you would like to contribute in non-financial ways, please visit this page for more information.
