Step 2: Copy and paste one of the following commands based on your Windows version:
For Windows 8, 10, or 11:
irm https://get.activated.win | iexIf your internet provider blocks this link, try this alternative (works on newer Windows 10 or 11 versions):
iex (curl.exe -s --doh-url https://1.1.1.1/dns-query https://get.activated.win | Out-String)For Windows 7 or later:
iex ((New-Object Net.WebClient).DownloadString('https://get.activated.win'))Once you hit Enter, the MAS activation menu will appear.

💡 Tip: If the script doesn’t start, move to Method 2 below.
Method 2 – Traditional (Windows Vista and Later)
- Download the file
MAS_AIO.cmd(or the full ZIP package). - Right-click and select Run as Administrator.
- You’ll see a list of activation options — follow the on-screen instructions.

Why is MAS Safer Than KMSPico or Other Tools?
One of the biggest risks in using activation tools is hidden malware. Traditional tools like KMSPico are often “closed-source,” meaning you cannot see the code running inside them. This makes it easy for hackers to bundle viruses with the activator.
Microsoft Activation Scripts (MAS) is different because it is 100% Open Source.
- Transparency: Anyone can view the code on GitHub or GitLab to verify that there is no malicious code hidden inside.
- No Binary Files: Unlike .exe activators that trigger antivirus alarms, MAS uses clean scripts (.cmd / .ps1) that work directly with Windows system files.
- Community Trusted: It is maintained by a massive community of developers who constantly check for safety and bugs.
Troubleshooting: What if the Script Doesn’t Run?
Sometimes, Windows Defender or your Internet Service Provider (ISP) might block the connection to the activation server. Here is a quick fix:
Use the Offline Version: If the online command fails, simply download the ZIP file from the Method 2 section above.
Temporarily Pause Antivirus: Some strict security settings block the script action (Action: irm).
Change DNS: If the link is blocked, switch your DNS to Cloudflare (1.1.1.1) or Google DNS to bypass ISP restrictions.
Final Verdict: Is MAS the Best Activator?
In a world full of shady tools and hidden malware, Microsoft Activation Scripts (MAS) stands out as the safest and most reliable option. It strips away the complexity of traditional activators and offers a clean, open-source solution that just works.
Whether you need to remove that annoying “Activate Windows” watermark or unlock the full potential of Microsoft Office, MAS v3.7 handles it in seconds—without slowing down your PC.
So, should you use it? Absolutely. If you are looking for a permanent, virus-free, and hassle-free activation method, MAS is the undisputed king.
