Fix MAS: Resolve Windows Service Issues for Activation

Fix Windows Services

Is your Microsoft Activation Script (MAS) encountering errors due to problematic Windows services? This guide provides clear, actionable steps to diagnose and resolve common service-related issues. We'll walk you through fixing corrupt 'sppsvc' and 'Null' services, ensuring your activation process runs smoothly and without interruption.

Corrupt service - sppsvc

Follow the steps below only if the script shows that sppsvc service is corrupt. Do not follow otherwise.
Download and extract the sppsvc registry file.
Run the file, restart the system (using the restart button), and try the activation script again.
If the issue persists, contact us here.

Corrupt service - Null

The script may show that Null service is not running, script may crash...
Follow these steps only if the script crashes after that.
Download and extract this Null service registry file.
Run the file, restart the system (using the restart button), and try the activation script again.
If the issue persists, check if you are using Comodo Antivirus or any type of sandboxing security software. If so, temporarily disable it and run the script again.
If the issue persists, contact us here.

Get MAS from the official project

This site does not host its own build of the scripts. The buttons below go to the project’s own repository and mirrors, so what you get is what the developers published.

PowerShell one-liner published by the project:

irm get.activated.win | iex

Check the domain before running it, and see how to verify what you run.

Activation tooling is routinely classified as riskware by antivirus software. That is expected for this category and is not by itself evidence of malware — nor proof that a particular copy is clean. Verify the source before running anything.
