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.

Download from official repositoryView official releasesView source

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.
