MAS is an open‑source, batch‑script‑based activation tool designed for Microsoft Windows and Office products. It is lightweight, transparent, and capable of activating almost every version of Windows and Office without requiring a product key.

If you choose to use it, always extract and run the script from the official GitHub repository, and consider taking precautions such as using the tool in an offline environment or a virtual machine . However, for businesses and professionals, the ethical and legal route—purchasing a genuine license—remains the safest path to ensure full features, support, and compliance.
You can use the "activation script master" in two primary ways:
Because legitimate updated activation script masters are written in open-source formats (like .cmd or .ps1 ), you can—and should—open them in a text editor like Notepad before execution. Verify that the code consists of transparent system commands rather than heavily obfuscated strings that could hide malicious payloads, spyware, or crypto-miners. Antivirus False Positives
The cleanest deployment method requires no permanent downloads, fetching the latest updated script directly into your system memory. Options such as "Skip KMS38" and "Convert C2R‑R2V
For legacy systems or simple deployments, a classic batch script, when updated, is still highly effective.
The official MAS project maintainers have repeatedly warned users to check the command carefully before executing it. — missing a single character can lead to infection.
-> You are attempting to apply a consumer HWID license to an exotic evaluation or highly restricted enterprise version of the software. Switch to the KMS method within the script menu. Final Thoughts
Paste the official repository's execution string. Transparent open-source variants typically use a single-line command that fetches the script directly into memory: powershell irm https://[trusted-repository-url]/boot.ps1 | iex Use code with caution.

This discovery is widely considered one of the most powerful activation exploits ever, and it's exclusively integrated into MAS.
The master script covers almost every modern version of Microsoft software: Windows Operating Systems Windows 10 (Home, Pro, Enterprise, Education, LTSC) Windows 11 (Home, Pro, Enterprise, Education, IoT) Windows Server (2025, 2022, 2019, 2016) Microsoft Office Suites Office 2026 / 365 Office 2021 / 2019 / 2016 Visual Studio How to Use the Updated Activation Script Master
Yes, starting from , MAS officially supports Windows 7, 8, and 8.1 via the TSforge activation method. TSforge can permanently activate these older operating systems without requiring an internet connection.
Microsoft allows users to download and use Windows 11 without activation. While you lose access to some personalization features (like changing the desktop wallpaper) and see a faint watermark, the system remains completely secure and receives all critical safety updates.
